So: I changed line 186 in sys/dev/ata/ata-disk.c from

adp->num_tags = atadev->param->queuelen;

to

adp->num_tags = 0x10;

which is roughly the half of the reported queuelenght (which is 0x1F).

And, Terry, I can't avoid to disappoint you... there's absolutely *no* 
change in the behaviour of the new kernel :-(

As I've reported earlier, the writecaching also makes no difference as 
does (not) changing the UDMA-speed (with 'atacontrol').

If you pretend on it, I'll change the DMA-speed with the IBM-tool, but 
I think we can do without it... (urghh, I would have to change to 
Windoze :-/ )

Sorry for the bad news, but... I think, we'll wait for Soren's commit 
tonight.
