I had the same problem.

I think it is just so that the partition is hidden from the normal
Windows installation and doesn't show up as a disk drive.  The default
ThinkPad MBR probably changes it to FAT if you press Access IBM during
startup, and then changes it back to the hidden ID on next boot.

Thank you!  This works on my T42 as well.

By the way, you can ask GRUB to change the partition type for you, so
you could have a GRUB menu entry that sets the recovery partition type
to 0x0b (FAT32) then boots it, and another GRUB menu entry that sets the
partition type back to 0x12 and boots Windows -- so that the recovery
partition wouldn't be visible as a drive in Windows, and you wouldn't
break it accidentally.

Yep, thanks again!
