2.4.21 does have native support most of the nforce2 chipset.  The only 
problem I have is with DMA.  The kernel recognizes the nforce2 chipset 
and sets all PATA drvies to DMA-udma2(33MHZ).  My PATA drives are 
100MHZ, and I cannot set DMA above udma2.  When I try udma3,4,5 I get 
"HDIO_DRIVE_CME(setxfermode) failed: Input/output error" .  This is with 
"AMD and nVidia IDE support" and "AMD Viper ATA-66 Overide" and "Silicon 
Image chipset support" all compiled into the kernel.

Funny thing with SATA.  If the SATA drive is not my boot drive, ie, it 
is an auxiliary, the SATA drive doesn't come up in DMA mode but I can 
set DMA to udma6 with hdparm and it works OK.  IF I BOOT FROM MY SATA 
DRIVE and the PATA drives are auxiliary, PATA drives come up in DMA 
udma2 and the SATA comes up in PIO.  When I try to execute "hdparm -d1 
-Xudma6 /dev/hde" I get all kinds of I/O errors on the /dev/hde(this 
worked fine when the SATA was an auxiliary).

So 2.4.21 seems to mostly work, and the SMGL spell "NVIDIA_nforce" 
compiles and ehthernet and audio work fine.  However, disk transfer 
times seem lower than they should be.  'hpdarm -t /dev/hda(PATA 100MHz 
drive) gives 25MB/sec."  "hdparm -t /dev/hde(SAGA 150MHz drive) gives 
52MB/sec."

Another point.  I emailed Nvidia support about 2.5.74, and they said 
they said, "Yes, there are compile problems with nforce2 linux drivers 
and 2.5.x, but they will support 2.6.x when it is released."  I hope 
they support the beta versions of 2.6.x.
