scroll bars flashing in konqueror (home dir)

[Matt <mattlist@fastmail.fm>]

hello, i just installed the 2.4.16 kernel image on my woody system.  along 
with it the new matros frame buffers for my mystique video card.  since then 
whenever i open my home directory (from the pannel, or command line using: 
"kfmclient openProfile filemanagement") the scroll bars are nothing but this 
flickering gray area.....and the window is hung.....i have to kill konqueror 
to get rid of the window.  

has anyone heard of this problem?  i can't find a single mention of it 
anywhere.  

thanks,
-matt
