Yeah,

my problem is that it shows *udma2 (udma-33), with using_dma
on...

Strange, no?

Could it be an IRQ problem? `dmesg | grep dma` shows (I've
touched the cable so the machine booted in UDMA-100 mode):

PDC20269: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode.

So maybe the old SB card?
