To reproduce the problem, install the "kbd" package, and from the first
virtual console execute the following command:
setfont lat1-08 # or any other 8-pixel font
Then switch to the second console and see that the cursor disappeared.
Moreover, the following escape sequences function improperly:
echo -e '\033[?Xc' where X is a digit
Even more, from the second console this command
setfont lat1-16
gives 43 screen lines with only upper halves of characters (bottoms are cut,
and I suspect this also happens with the cursor).
Looks like a bug in the character cell height logic. Could you please fix it
or at least point me to some overview of the relevant source files?

Forgot to say that this bug is reproducible only on non-framebuffer console.

This bug seems to be Radeon-specific (doesn't exist on ATI Mach64). But even
on Radeons, it can't be reproduced in 2.4 kernels - so it's a kernel bug.
