You patch helps a lot because the new kernel is now able to boot, with
the DMA enabled. I have the impression that there is still one 
problem because when I enable ATA66 (with hdparm -X66) I have the following
error message:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----
hda: dma_intr: status=0x5a { DriveReady SeekComplete DataRequest Index }

hda: dma_timer_expiry: dma status == 0x21
hda: timeout waiting for DMA
hda: timeout waiting for DMA
hda: (__ide_dma_test_irq) called while not waiting
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hda: drive not ready for command
-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

Do you have an idea of the meaning of this message?

Anyway, many thanks for your help.
