This is not always true, there are SRM versions which are perfectly
able to boot from IDE drives (it is definitely the case for LX164, I
would bet it is also true for miata and sx164 too, and maybe others).

And IDE performance with the newer kernel is not that bad with DMA
enabled (I have not done extensive measurement, but a bonnie result
was not far to what you get with a PII PC using the same disk, the
Alpha was maybe about 10% slower). You need to compile the kernel with
the right chipset support.
