No, it was not the BIOS. Those alternatives are correct.
No, it was not the cables even though putting in the 80-pin cable is more 
up-to-date and the bootup no longer complains about that.

The MB is a via chipset. Ide-generic, compiled into the kernel, is not 
compatible with this. So I compiled the kernel with the via module compiled 
in, leaving the generic as a module in case it is needed as well (not using 
an initrd but would be needed there as well, i think). A few trepidations 
here but it boot up just fine and no more complaints about DMA. Phew! I can 
breathe again :-)

(There were several googled items citing this as the only solution.)
