7.2-PRE: switch virtual console drops crazy characters into X

Hi all,

to make a long story short, I got trapped in the Xorg upgrade
problems (concerning HAL etc.) that were widely reported during 

After reading thru the material I figured out that there are
not much chances that somebody would take effort and fix these
things for a 6.3 Release.
So I decided to give it a try with the 7.2-PRERELASE. And, well,
after recompiling all the stuff, the problems seem gone so far.

Only one strange thing has appeared:

Every time I switch from X to a virtual console and back, I get
some characters dropped into my command-line in the X window,
and have to delete them with the backspace key.
These characters read: ^[[20~

Now this is exactly the escape sequence on the F9 key (where the X
runs), if it were pressed without Ctrl-Alt. That shouldn't happen.

Now the funny thing is: this does only happen when booting the
GENERIC kernel. When I boot my normal custom made kernel, it
does not happen.
Now this is strange. Usually the GENERIC kernel should show the
least unexpected behaviour. 

Alright, there are lots and lots of devices left out of my custom
kernel, but I do not see anything that could have to do with 
VT switching. I do not quite understand it. But I am also not
so much bored that I would start trying out options and building
kernels so to find what makes this happen.

So, if anyone experiences the similar thing, and is enough annoyed
to do something about it, I will happily send a diff from my
kernel configs.
