Thanks for everyone who gave me pointers on running XFree on my
AlphaStation 500. I'm running 1.6K, and downloaded the XFree 4.2.1
sources from www.caseydoodle.com, and set up my kernel config
accordingly. However, there are some glitches.
1. dev/ic/vga.c does some things differently for __alpha__
Especially irritating was the fact that it sets up the
firmware blue as background color, and this really does
not do the right thing. Depending on what I run on the
console, the screen is sometimes with black background,
sometimes with blue, and sometimes its mixed.
For example, I start NetBSD and the background is all
blue. I run "more <whatever>". The first page comes up
with blue background, the next with black etc. Then
running somethings else (for example, logout, after which
login runs) the background starts going blue again.
If I run "vi", the background is blue, but if I run
"vim" and it does its own syntax highlighting, the blue
background messes everything up very badly.

at around line 455 in dev/ic/vga.c gives me sensible,

8 bit mode, white colour appears as blue. 16 bit mode
is OK. (I tried running X with noaccel, and it didn't
4. PCDISPLAY_SOFTCURSOR does not do the right thing after
I exit X. IOW, I see both the soft cursor and the blinking
cursor which stays always at the upper left corner of screen.
