more kgicon...

Hi,

I wrote yesterday mentioning my difficulties getting kgicon to work;
after more experimenting, I can get a nice black screen in 1bpp mode.
the keyboard is still usable, _as long as I don't run con2fbmap_ .

# cat /proc/fb > fblog     at this point gives

0 VGA+
1 KGI

however, if I do a 'con2fbmap 0 1', I stop getting any response from
the keyboard, and the screen stays black.  
The computer isn't locked up though, because if I instead 
run a command like

# con2fbmap 0 1 ; sleep 2s; con2fbmap 0 0
it works okay.  Also, I can 

# rmmod kgicon.o ; textmode

and that gets me my text mode back.  
Here's a clip from my syslog.
I've cut some lines because I was on DEBUG level3...

so, what's wrong with con2fbmap?

many thanks,
