I can see reverse-video question mark on LFS box, but reverse area is square
in firefox/gmail and oval in lfs (I assume due to different font)

My console file:
# Begin /etc/sysconfig/console
FONT="LatArCyrHeb-16 -m 8859-15"
# End /etc/sysconfig/console

# Begin /etc/profile
export LANG=en_US.UTF-8
# End /etc/profile

- inputrc exactly as in the book
- rc.site has no console parameters set

Well, I've decided to look out of the box and changed keyboard from
usb to ps/2 type - no difference.

However when I tried to boot from exactly the same HDD on another
motherboard from different vendor - everything works fine! It doesn't
work on recent Atom D2550 motherboard and works on old D510 and
on HP desktop with Core2. New Atom board has Intel ICH10R chipset
and NUVOTON NTC6776D SuperIO, while old one has Intel ICH9R
chipset and Winbond 83627DHG-P SuperIO.

Does it mean the problem might be with some kernel drivers?
