[PATCH 2.6.13] drivers/ide: Enable basic VIA VT6410 IDE functionality

[Robert Kesterson]

This patch enables plain IDE functionality on the VIA VT6410 IDE controller
(such as used on the Asus P4P800 Deluxe motherboard).  This is not a RAID
driver, but you can use Linux's software RAID once the drives are visible.
I did not write the original version of this patch, which I found on the
internet back in the days of kernel 2.6.2.  I have been unable to identify
the original author to give him/her proper credit.  I have been maintaining
and updating this patch since then and have released several updates which
have been successfully used by others who have downloaded it from my
website.

It seems appropriate that this minimal functionality should be in the
mainstream kernel.

Mathias Kretschmer posted a patch several months ago, and Daniel Drake
reposted it on August 30th if you check the archive. Bartlomiej was
asked to respond to/merge it but if he responded I didn't see it so it
was probably a private reply.

You can pull it from the Gentoo tree and it'll drop into other vendor
trees cleanly.

Thank you, I have been running with a similar patch for 2.4 series, but 
have been running unpatched kernels for testing and have not had access 
to my other drives. Hopefully this can get into the mainstream without 
too much delay.

No, this patch is an earlier reincarnation
(it changes generic.c instead of via82cxxx.c).

Bartlomiej responded the same day (cc:ing linux-kernel and linux-ide)
and asked Daniel to fix via82cxxx.c to support multiple controllers.

Daniel sent me patch 2 days later but I still need to go through it
(I've been away for 3 weeks).

After using this patch (it works), it comes to me that the 2.4 version 
was in a separate driver, so I can control my order of controller 
recognition. Just having access to the devices is useful, but it would 
be more useful in the module version.
