David, the following refers to development kernels...

 This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C         
 onboard chipsets.  It also tests for Simplex mode and enables           
 normal dual channel support.                         

So if you want the support you'll have to use a development kernel.
I suggest 2.3.5 as it was very stable for me and was the lastone before
they started major FAT filesystem changes. Anykernel after that can't
write to a FAT partition. (2.3.13 can read from one though).
