fbdev/linvtsw problem

	I have been seeing this problem for a while now, and since I just did
a fresh degas checkout and install on my box which was just upgraded from
Redhat 5.2 to 6.0 and the problem is still present I guess I'd better bring
it up.  The problem is that I cannot run any GGI apps using the fbdev target
unless I am root.  I have set the permissions on /dev/fbx correctly.  Another
odd thing is that XGGI 1.6.0 still works fine!  Only programs built against
LibGGI within the last month or so on my system exhibit this behavior.  

	What happens is that the program hangs until I do a VT switch,
whereupon I get a signal 11 error message when I switch back and the program
has terminated.  Using the X target, everything works fine.  Wierd.  I'm
using the vesafb/2.2.5-15 (redhat 6.0 default kernel), but it happens even if
I load a KGIcon driver.  It is easy to get around the problem by running 
everything as root, but that shouldn't be necessary.  Anway....

Here's the GGI_DEBUG=255 output (demo.c):
