I've got a DECstation 5000/25 w/40MB RAM and console on a PMAGB-B
running 1.5Alpha kernel (userland WAS building for about a day and a half
until this) and an LK-501 AA keyboard and a VSXXX-BB mouse. Pushing Do in
X causes an andless stream of panic: panic: panic: panic: etc. Pushing it
at the raster console causes an endless stream of panic: TLB miss or
just plain freezes the whole computer. (If I get a TLB miss, I do
not get sent to db> it just loops) The dtop driver has been acting very
poorly in 1.5Alpha. Almost every time I move the mouse I get overruns, and
just typing will ocasionally cause them. Can someone take a look at this?

	The reason I was pressing the Do button was to test xmodmap
changes by xkeycaps because somones changes to keyboard mappings have left
all DEC LK-xxx keyboards with no working delete or backspace. There was
discussion on this a while back, but no one has done/said anything on it
for weeks so I send-pr'd it.
