Hallo Juergen,

I'm using a "home-grown" 2.4.21-pre5-ac1 with XFS (CVS-2003-03-05).
Alan's patch removes nvidia.* from drivers/ide/pci (pre5). It includes 
nForce(2) support in drivers/ide/pci/amd74xx.* so be sure to activate "AMD 
Viper support".

For now I could say it works stable and fast on my Leadtek K7NCR18D-Pro
(nForce2):

[root@cobo-1 root]# hdparm /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 7476/255/63, sectors = 120103200, start = 0

[root@localhost root]# hdparm -itT /dev/hda

The box isn't really under stress but it serves my imap stuff and I'm coding a 
lot with Eclipse and compiling new kernels every hour ;-)

Hope this helps...

Cheers
Thomas
