Um, this is NOT the Peintium bcopy problem.  Setting flags 0x01 to
npx0 won't solve this.  In fact the user cannot even reach the kernel
configuration menu.  

This problem is cased by the video paramter table in the video BIOS is
not organized the way syscons expects.  SpeedStar 64 is known to have
this problem.  The workaround code is committed in syscons.c
v1.182.2.18, thus, 2.2.2 is OK.

As the user already installed 2.2.1 using a different video card, I
suggest him to apply the following patch to syscons.c (in
/sys/i386/isa) and rebuild the kernel.  Then, the box will boot fine
with SpeedStar 64.
