I don't think so.

In grub the equivalent for 0x80 is (hd0) and for 0x81 it is (hd1).
You can use device maps to map these BIOS drives to the corresponding
linux devices.  For this you should create a /boot/grub/device.map
file containing the following lines:

(hd0) /dev/hdb
(hd1) /dev/hda

Then start grub with the commandline parameter
"--device-map=/boot/grub/device.map".

This becomes:

# grub --device-map=/boot/grub/device.map
root (hd0,1)
setup (hd0)

And don't forget to change menu.lst.  Keep in mind that /dev/hdb is
accessed with (hd0) and /dev/hda with (hd1).
