pff font path on separate partition

[spamgrinder]

Hi,

I use version 1.96+20080724-2 grub-pc Debian package. After executing
update-grub I receive line in grub.cfg

if font /usr/share/grub/ascii.pff ; then
...

which is incorrect because my /usr partition is other than root partition.

I have disabled graphic mode in result, because at boot time this path
doesn't exist of course.

Path to font should be (hd0,5)/share//grub/ascii.pff.

At this time in /usr/lib/grub/update-grub_lib, function font_path, "for"
loop,  I restricted a set of directories to /boot/grub only /

Regards
