Sorry for confusion. I have commented GRUB_TERMINAL (as in default
configuration), but still 1.96+20090808-1 is using text mode anyway.
Hongzheng Wang also have this problem.

In 1.96+20090826-3 I have this unaligned pointer error with
GRUB_TERMINAL commented, but still grub is using text mode,
and unaligned pointer error happens after loading any kernel
(i think initrd isn't loaded), then i can press any key, and restart
boot process (it backs to bios quickly, it read MBR again, and load
again grub).

No gfxmode is used at any point (with or without error, in any version).

why this is in /usr? i have /usr and all other filesystems fully
encrypted. Only /boot is available from grub.

Will try after work. I already compiled grub-pc from gnu-svn+debian-svn
with your 1bit_blitter.diff patch applied (which removes few function).


PS. 1.92 was a typo, everywhere i should write 1.96.
