Ah - excellent idea.
I'm helping get IDE-CDOM working and I have also started work on
getting the built-in narrow scsi working (sym53c8xx driver needs
to make a PDC GET_INITIATOR call).

To debug problems like this, enable EARLY_BOOTUP_DEBUG in
arch/parisc/kernel/pdc_cons.c.  We also need you to keep the matching
System.map and look up where IOAQ and GR02 point to in the kernel.
Use "build-tools/a.c" to help do the look ups.

I've copied kernels for c3k (32-bit) and a500 (64-bit) to my ftp server.
I've stripped out stuff neither needs from their respective .config:
	ftp://gsyprf10.external.hp.com/pub/a500
and
	ftp://gsyprf10.external.hp.com/pub/c3000

DISCLAIMER: I don't guarantee these kernels will work for anyone for any
purpose or that they are "clean" builds (ie may have custom changes).
Just providing them as a convience.

If something is missing from the respective .config that you think
I should include, feel free to ask for it. I might include it. ;^)

CBFB is the "chassis code" for the fault.
Don't recall what that means but it's documented someplace.

The "785/B2000" is written by firmware.
Kudos to Helge/Randolph for the code that writes the top line.
It is cool!
