Already pre5? Time to upgrade, I have only pre3 :).

If I understand the DMA mode correctly, it needs some help from the IDE chip (as
in Intel 430HX and above) and from the docs I had about OPTi 621, there is no
support for DMA at all. The driver I wrote only sets (tunes) PIO timings. So, I
don't know why the generic DMA driver is enabled (I don't understand how it
works). Maybe the newer chipset with Opti Viper does support DMA, but I never
had it, I tested the driver only with PCI add-on card (on old 486).

Do not compile the driver into kernel :).
