Just tried the patch with the 2.6.0 kernel and it didn't help. As a bonus 
"feature" the cursor also makes the character it is underlining blink.

I assume that something broke in 2.5.51 on some cards (maybe while making 
fb-con modular?). Three of the four people who stated they had this problem 
had a ATI card (two had a Radeon 7500 and I have a Radeon 9500 and one didn't 
include the videocard). :( 

I have no idea what change could be the cause.

If I could help you with more info please say so.

Thanks again,

S Ait-Kassi

I have before but I only got a blank screen. I just tried it with the latest 
patch and it does work and doesn't exhibit the problem but has a couple of
drawbacks. The ACPI information and the start comes up distorted probably 
because the framebuffer is getting initialized. I either get characters a 
mile apart. (i.e. i         n                      f                       o) 
and I just got some colored confetti instead of (ACPI) information. 

That's not really my biggest problem because that would be the fact that my 
tv-out isn't working. Looks like it's out of sync. The documentation on how 
to control the framebuffer seems to be lacking somewhat. I don't no if the 
ati-setup which was reintroduced could help me there? (I couldn't find it by 
the way) The append="video=radeonfb:1024x768-24@85" doesn't seem to work
for me in the lilo config (I also tried radeon instead of radeonfb). I only 
get a reolution 640x480 screen @60hz. The vesa framebuffer seems to be able
to control the tv-out independent of the resolution of the monitor. I don't 
know if it's an issue with the radeonfb or that it just not featured?

Thanks,

S Ait-Kassi

Hi,

I'm mailing to inform you of a possible bug in the vesa framebuffer module 
which has been appearing in the kernel since 2.5.51. I posted at the
linux-kernel@vger.kernel.org mailinglist but wasn't able to get feedback so 
I'm directing it directly to the developers of the framebuffer layer and to 
you specifically since you were involved with most of the changes in 2.5.51.

I have attached grabbed framebuffer distortion pics (png) since I think those 
speak clearer than my previous attempts to put the problem into words through 
the mailing list. 

Hope you can shed more light on the situation.

Thanks,

S Ait-Kassi

Hello,

I figured out in which kernel the problem I was having appeared. It seems to 
work with 2.5.50 and the problems starts with 2.5.51.

I've looked at the changelog and showed these changes that might have 
contibuted to my problem;

-There are some changes in fbcon. Made modular along with some fixes and some 
vesafb fixes.

-Accel wrapper is now intergarted into fbcon.c. VESA fb fixes 

-Made fbcon modular.

-New NVIDIA and Radeon cards pci ids. Soon I will add support for these :-) 
Also a needed fix for fbcon.c. 

-Moved AGP and DRM code back to drivers/char until a proper solution is done 
for handling AGP/DMA based framebuffer devices.

Almost all changes by the same developer <jsimmons>. I've been looking
at the source differences but the introduction of the fbcon module really 
complicates the matter.

I was wondering where to go about reporting the 
problem or where this issue might stem from. (i.e. the includes shown in 
vesafb.h, vesafb.h itself, fb.h or the fbcon module related code.

Or would it be best to just mail the developer? :)
Any help is appreciated.

Regards,

P.S.: Here is the part of my original mail describing the problem. It has been 
confirmed by two other submits to this mailinglist regarding the 2.6.0-test4 
kernel. I'm using the 2.6.0.-bk3 kernel myself.
