I had been looking hard at the Abit SU-2S, with the Marvell 88SX6081
on board.  Is this to say that the Marvell chip is also in the latter
category of "slow annoying PATA-like crap"?

Does anyone know an AHCI controller that can be attached to a dual opteron
motherboard?  All of the ones mentioned seem to be built into Intel
chipsets.

Thanks!
