Subject: mpc823 w/lcd performance

Hi,
Should I have reasonable performance running a MPC823 with the LCD
controller driving a 640x480 color TFT panel? The reason I ask is that I
compile the kernel with lcd823.c (pulled from Wolfgang's ftp site)
selecting the SHARP LQ64D340. The system slows to a crawl. I calculate
the LCD using 26% of bus bandwidth. But, it appears to be using much
more. I haven't actually hooked up the panel yet (waiting for cabling).
Kyle.
