Nice.  Is that controller in the PCI bus?  It's strange that you got it
working on real hardware (i.e. not qemu) because PCI wasn't implemented

Yes.  However, I'm saying that grub2 works as of today, not 10-31.

The other Athlon machine has one PATA drive on a VIA 8235 controller
and one SATA drive on a Promise controller.  This machine makes it
through grub_ata_dumpinfo for both disks but then it hangs forever
without printing anything else.

Could you re-run this part with `debug' variable set to `ata'
("set debug=ata", then "insmod ata") and see what's the last thing
printed ?

Ah, I didn't notice before that grub2 only recognizes the PATA drive
and the cd-burner on the PATA controller.  Grub2 stops dumping
info after the cd-burner and never gets to the SATA disk on the
Promise controller.  The Promise controller is built into the mobo
and the BIOS recognizes it and will boot from it, but the ata module
in grub2 will not.  Would this explain why grub2 hangs?

I should mention that I've never installed grub2 because I don't
really want it on my boot record yet.  I build the grub2 image using
./grub-mkimage -d . -o mygrub *.mod (as I read on the wiki) and then
use old grub to load grub2.  I loaded ata.mod by accident because I'm
too lazy to type all of those module names :o)  I certainly don't
mind testing and debugging the ata module, though, if I can be of
any help to you.
