does XFree support event?

also there dual boot 2.4/2.6 systems where you have single XFree config
and single gpm config ... although these will have problems with
non-imps2 mice anyway.

Anyone does dual boot with non-imps2 mouse BTW? I am interested in how
people handle it.

TIA

I don't know but patches have been floating around for a while for 
XFree86.

Once everything starts using the event api we will not need configs 
anymore when it comes to input devices ;-)

kYes it is fine. That is a PS/2 aux emulator. It turns non PS/2 mice into 
PS/2 mice. Personally I rather have people use the /dev/input/eventX 
interface. That PS/2 hack will go away in the future. 

P.S 
   CONFIG_INPUT_EVDEV is not turned on by default. It should be IMO.

No it is not. I had to set CONFIG_EMBEDDED on my P4 (definitely
not embedded) to get rid of PSAUX. My P4 uses a nice serial mouse,
and I neither need nor want kernel mouse support.

I can understand the desire to provide safe defaults for newbies
doing oldconfig on 2.4 .configs, but the !EMBEDDED implies mouse
change is too rigid.

I don't have CONFIG_SERIO_I8042 enabled at all, since I'm compiling for a m68k
box without i8042. But it does compile/link.

there are problems. See

http://marc.theaimsgroup.com/?l=linux-kernel&m=106047737716122&w=2

mouse/atkbd depend on serio driver (i8042) so if i8042 is module and they are 
forced to be builtin the whole story does not work.

apparently there are people who build them as modules

Now INPUT_MOUSEDEV_PSAUX is always (on non-embedded machines) forced to true,
even on machines without PS/2 keyboard/mouse hardware. Is that OK?

So far (compiling, not running 2.6.0-test3) I didn't notice any problems,
though.

Actually, I was going to move all this stuff to the embedded menu as soon as I 
caught up on Linux-kernel to make sure nobody else had already done it.  (I 
was only 2500 messages behind the day before yesterday, but people keep 
posting more... :)

Finding out that Alan beat me to this is exactly why I'm catching up on my 
reading before pushing patches. :)

The 2.5 kernel I just compiled is currently about three times larger than the 
uclibc+busybox root filesystem I built yesterday.  I'm all for stripping it 
down, but saying that your average server doesn't need the ability to plug in 
a monitor and keyboard and see what's up if it suddenly goes peculiar...  
Well, I wouldn't want to support that system, and certainly Red Hat ain't 
gonna ship like that any time soon.  (As for the servers you mentioned in 
your previous post, we're potentially saving tens of kilobytes by doing so, 
on a system with around gigabyte of ram.  So if we're saving 10-30k (not just 
kernel code but run-time allocations), we're talking about saving 0.001 to 
0.003% of ram on a server setup.  Oooh.  Aaaah.  Definitely the kind of 
micro-optimization we want everybody in the world (and their dog) to have to 
figure out if they need or not the first time they compile a kernel.)

Again this is stupid.  With the select CONFIG_INPUt if CONFIG_VT people
get this asked now on make oldconfig.  Even more important many ports
newer used PS/2 style mouses previously as did older PeeCees.

Please stop this over-eager spreading of CONFIG_EMBEDDED, we're not
gnome..
