Actually, it's worse with the new driver; even the harddiscs that got
20MHz now only get 10MHz, only my DVD drive gets 20MHz. Weird.

I'll attach the relevant parts of dmesg output of the old and the new
driver, where the rest of the kernel sources was cvs updated about an
hour ago.

I'm willing to test any changes, if I don't have to stress-test them,
since it's my main machine.

Bye,
 Thomas
