I have been using a Asus K7M motherboard for a while, and I have nothing
but positive things to say about athlons. Both Linux 2.2.x and 2.4test
works perfectly (in 2.2.x I can't get the IDE drives above UDMA33 mode,
but my IDE drives does only about 24-25mB/s anyhows so it's not really a

The IDE code fallbacks on PIO by default using this IDE chipset (VIA) in
2.2.x, but can be set to UDMA33 with the -X and -d option to hdparm.

My setup here at home is a Asus K7M mobo, 700Mhz Athlon, 512MB PC133 CAS 2
SDRAM, a Tekram 390U3W dual channel u160scsi card (guys - I need a 2.2.17
driver for this baby, LSI/Symbios 53C1010-33 chip), and a g400 max dual
head (which is by the way a great card for XFree use).

This motherboard is one of the first athlon-boards around, so it only runs
the RAM at 100Mhz, uses a slot A instead of the socket A, lacks the latest
chipset improvements and supports at most UDMA66. I can't speak of newer
athlon motherboards - because I havn't tested any else yet. This baby will
do for a while :-)
