I don't see such a problem with grub-emu on PC. I tested the current CVS
version. I made a hard disk image with ext2, put a 20MB file on it and
run "cat (hd0,0)/foo" with the output of cat disabled (I modified the
code). It took about 2 seconds on my laptop. Since my disk is really
slow, I think this is normal. I did this test after I "cat" two ISO
image files to /dev/null to flush the cache of the hard disk image.
So I guess it is specific to PowerPC.
