Thanks.  Tried it - no joy.

NoMTRR is not actually a valid option for the Silicon Motion driver, version
1.3.1.  The option seems to be ignored by the driver.

I did notice one oddity in the log file.  Where the driver reports the probed
size of "videoram" and doesn't accept a "videoram" option, the size reported is
4096kB.
 (--) Silicon Motionvideoram: 4096kB

The "fbdev" driver, on the other hand, reports only 3072kB for this hardware,
which is exactly 4 bytes per pixel for the 1024x768 LCD display.
 (II) FBDEV(0): Hardware: VESA VGA (vidmem: 3072k)

How much memory is there, really?  There's a problem if 3072k is all.
