Hi, all

I've completed WSCONS PMAG-J (TX) support in dev/tc/tfb.c after I was
given a TX board by a kind guy.  Tested good on DECstation so far, but
not examined with TC alpha, yet.  It could be used as 8bpp
non-accelerated dumb framebuffer.

TX has two framebuffers inside, 8bpp and 24bpp, and a bitmap plane
selects any portion of two framebuffer images onto a screen.  It's
interesting to know TX has more than 8/24bpp hardware.  The emourous
single slot TC option card can be used for video capturing counting
virtical retrace interrupts by special IOCTLs.  That function has not
been under research.
