>Description:

	kept old kernel config for a while ..
	made cvs-update .. 
	rebuild the kernel
	kernel boots fine ..
	startup is fine ..
	serial console seems to be ok ..
	but:: vga-console:
	login: .. i try to enter the login-name
		i am not able to enter more than 3 characters
	kernel locks up ..
	message on the console about pckbd: lost <sth> ..
	serial console locked as well now ..
	strange enough .. in-kernel-debugger
	 on serial line still works
	sync .. (get a kernel panic .. but .. that is a different issue)

	I would guess .. using a serial console "helps" as well ,-)

>Fix:
	i changed
	wsdisplay*	at vga? console ?
	to:
	wsdisplay0	at vga0 kbdmux -1 console ?
	
	i am not experienced enough to dig into the source code
	.. am willing to apply patches (kernel build takes about 1h though)


	thank you very much in advance
