Yes.

$ find . -type f | xargs grep -l ANAND
./root/lib/modules/2.4.19-eipm/kernel/drivers/block/doc.o
./root/lib/modules/2.4.19-eipm/kernel/drivers/block/doc/doc.o
./root/usr/lib/grub/i386-pc/stage2
./root/usr/lib/grub/i386-pc/grub_firmware

After inspection, grub_firmware does have 'ANAND' at offset 87040 (170 *
512).

I'm happy to test any patch since I can reproduce the problem here very
regularly ... :-)

I'll do that to check it.
