Here I would like to mention the man page polling(4) for clarification (it does
not look like the GENERIC kernel can do polling...).

Furthermore I would like to know, how fast is a "dd if=/dev/discXY of=/dev/null
bs=64k count=1000" in single user mode on your box (I can do 42.8MByte/sec with
UDMA-100 and ST340015A (Seagate?))...
