Linus,

Please accept the attached for 2.5.46.

It introduces a new boot parameter (eg. ide0=biostimings) that forces the
IDE driver to honour BIOS DMA/PIO timings. Sometimes the BIOS has a better
overview of how the IDE devices are connected/setup and some chipsets doesn't
support >ata66 speed detection.

The patch has been tested for quite a while on both PIIX and serverworks.

Torben
