OK. Possible I'll get free time next week and can do something :)
I have some questions:
1. Memory limit that was argued not long ago. I think that memory size variable should be 64-bit size and also full mmap support would come... I can try to do it.
2. Also I have a question about disk offsets. Now it is 32-bit and it's OK for dos and apple maps but doesn't enough for another partitions map such as LDM. Of course LDM doesn't available for GRUB now but perhaps it will come in future. Replacing to 64-bit offsets seems to be not very hard but a complex work. Also it seems that block_list stores block number as 32-bit.
3. amd64 compilation. It seems to be not available now. One more question I have... Linux gets device geometry througth the ioctl call. Does the "long" type for "start
field in "hd_geometry" struct (that used is util/i386/pc/biosdisk.c) is always long type (that means it is 64-bit for amd64) or just 32-bit type? I'm not Linux specialist and don't know...
