5.3/AMD64 fails to detect ARAID-99 PATA unit when booting Tyan S2882 from a SATA drive

[Cesium]

Yesterday I received hardware to complete a Tyan S2882 based system.  In just a few hours I had FreeBSD 5.3-STABLE / AMD64 running with all memory and processors accounted for.  

I have two hotswap IDE RAID devices installed.  I have an old ARAID-99 from the previous 4.x system where it worked fine.  I have a new SOHORAID based on the same electronics, but with a SATA interface.   Last night I installed FreeBSD 5.3 on the new SATA unit because the drives were new and empty.  Later I intend the ARAID-99 to become the system volume and the SOHORAID to function as the data volume.  

Because the Tyan BIOS is weak concerning boot devices I had to go into a screen and make the SATA controller the #1 IDE device and the PATA controller the #2 drive.  Then I was able to boot off the SATA image with the PATA unit installed.  

The BIOS screen detects the ARAID as the IDE primary master prior to the SATA boot cycle.  FreeBSD does not.  There is no /dev/ad0 as I expected.  I've booted with blank drives in the ARAID and with older FreeBSD 4.x drives installed.  

fdisk / diskinfo / disklabel won't show me ad0.  They all complain that the device does not exist.  I tried to fake it out with makenod but then I got "device not configured".  I'm not too strong on devfs yet and there is presently no man page for devfs.conf  

Aside from this issue, so far my experiment with 5.3 / AMD64 was a complete success.  

Is there some reason under 5.3 that SATA and PATA drives don't coexist well?  I'm uncertain what to try next.
