Well, the driver seems to work good enough for now to use a serial
console. And the SysRq support is an absolute must when trying to debug a
locked-up kernel -- the lack of this support is a sign for me nobody is
currently working on DECstations at the moment.

Hmm, I haven't noticed any, either. Fixing the driver is actually on my
TODO list -- all the 8530 drivers present in Linux currently need to be
merged into a single one. Also DMA and synchronous mode support has to be
implemented. It's not on the top of my list, though.

It's actually the reverse. ;-) Without these (oh well, sunkbd.c is for
completeness, indeed) you cannot compile-in the magic SysRq support if you
do not include the virtual terminal driver. This is an unnecessary
limitation -- I don't want the VT (well, actually I would, if I had a
driver for my console, but I haven't, yet).
Such changes actually went into the Linus' 2.4.0-test6-pre* (but not mine
-- someone overtook me, and he also missed one bit ;-) ).
