I'll try my best.
Being that I'm new to GRUB, that's probably not very good ;-).

Incidentally, could you perhaps offer your comments on the attached patch?

It should enable GRUB to detect the correct number of sectors on
device-mapped devices, seeing as the BLKGETSIZE ioctl seems to work on
those, but HDIO_GETGEO doesn't.


One thing I can think of myself is to actually calculate the "correct"
cylinder count with 63 secs/track and 255 heads, instead of just using
the large drive placeholder values of 1024/255/63.  Not sure if it
matters any.
