Re: status grub2 port of grub-legasy map command

Hello there. I am the original author of the drivemap command. I was
told by a friend that it was being discussed again on the GRUB list, so
I came back and examined the two new enabling functionalities, preboot
hooks and mmap. I've adapted drivemap to use them both, and I'm
polishing some rough edges. I might send a new version of the patch this
weekend. Should people, however, prefer John's version, I'd be glad to
assist.

The preboot hooks patch works beautifully. However, mmap causes some
sort of glitch that makes FreeDOS (one of my three drivemap tests,
together with ReactOS and XP) triple-fault. I've been trying to debug it
with GDB-over-QEMU, but it is a real PITA. I haven't found any sort of
bug in the mmap code, so I'm quite dumbfounded right now. Nevertheless,
I'm proceeding to the XP test, which would likely be the most common use
case for drivemap.
