What about this:
* commands/i386/pc/drivemap.c : New file, main part of the new
drivemap module allowing BIOS drive remapping not unlike the
legacy "map" command. This allows to boot OSes with boot-time
dependencies on the particular ordering of BIOS drives or
trusting their own to be 0x80, like Windows XP, with
non-standard boot configurations.
* commands/i386/pc/drivemap_int13h.S : New file, INT 13h handler
for the drivemap module. Installed as a TSR routine by
drivemap.c, performs the actual redirection of BIOS drives.
* conf/i386-pc.rmk : Added the new module
* include/grub/loader.h : Added a "just-before-boot" callback
infrastructure used by drivemap.mod to install the INT13 handler
only when the "boot" command has been issued.
* kern/loader.c : Implement the preboot-hook describedBy the way, I sent the data to the "assign" mail as you instructed me to, and I've been told I'll receive some GNU copyright assignment documents to sign-and-return in a few days.
