	I have the same question (see start of my dmesg later on).
My motherboard is Gateway's GA-586DX.
I can not see any settings about IDE-DMA in BIOS setup :-(

And the next one - when I try to set flags on wcd0 to '0xa0ffa0ff'
the system can't start - I receive:
panic - can not mount root (?) message.
	Is there any possibility to avoid this panic and
fall back to PIO-mode ?
