[Soekris] ad0 dying during bootup w/FreeBSD 5.2.1 on 4801

[ray@atnip.net]

Ok, I have a difference on the boot outputs.
The Sandisk that boots and runs fine shows
ad0: 245MB <SanDisk SDCFH-256> [980/16/32] at ata0-master PIO4
the CF that fails during boot shows
ad0: 245MB <SanDisk SDCFB-256> [980/16/32] at ata0-master WDMA2

So my new (or another) question is why is one showing a PIO4 and the
other a WDMA2?
