--- Comment #11 from Silas S. Brown <silas-kde at flatline.org.uk> ---
Just found a RedHat bug report of the same problem:
https://bugzilla.redhat.com/show_bug.cgi?id=495323 (that Thinkpad and my Eee
both use the same Intel 915GM graphics chipset).  This report mentions a
workaround of disabling KMS (kernel mode switching), which can be done by
adding "nomodeset" as a kernel parameter, for example by editing
/etc/default/grub and adding nomodeset to the GRUB_CMDLINE_LINUX_DEFAULT
setting (then run "grub-mkconfig -o /boot/grub/grub.cfg" and reboot).  I just
did this on an Eee and the broken fonts problem disappeared, but I got an
800x600 mode, which looks rather horizontally "stretched" on the eeePC's
1024x600 display.  (The report also mentions possible fixes in various 2.6
kernel versions, but I'm using a kernel that identifies itself as
3.0.0-32-generic and still have the problem.)

Fonts do seem to be much better (but not completely fixed) when I disable the
swap partition (by commenting out the swap line in /etc/fstab and rebooting). 
This is in response to a comment in the above RedHat report which mentioned
forcing a lot of swap so as to reproduce the bug more reliably.  The logical
conclusion of this is that DISABLING swap is a possible workaround.  I have 1G
of RAM on this eeePC, which is more than enough for what I want to do with it,
so I don't really need swap.  I don't understand why having swap makes the
glyph corruption problem worse, but I'm happy to do without swap if it makes it
better.  (Note that glyph corruption is still there even without swap, but it's
much less severe.  It might still be made a little bit worse after resuming
from suspend to RAM though.)
