I'm quite positive that you can use these fixed-frequency Sun monitors with
'SVGATextMode' [a utility for Linux], though i've never tried it.

[i already regret that i start the RISC/CISC flamewar :)]

RISC core CISC chips were good when memory was expensive.

Now that memory prices are low, i think highspeed chips like the Alpha
get viable. What made me shudder two years ago was that the OSF/1 kernel 
was 8MB and each executable was twice as big as on a CISC-ish machine.
Now that doesnt make much difference. And a clean RISC design is much
faster. Alpha is at 500MHz now, and Intel had to announce their ridiculous
1GHz vaporchip.

Now instruction compression doesnt buy you much but increased CPU die
size and lower throughput, so there is a real technological gap between 
RISC and CISC/RISC machines. Maybe some RISC vendor combines this with
some cool x86 emulation/dynamic translation technology, and cuts off
Intel's high end profits.

yes. the only barrier so far was that there was no server-size x86 chip.
With the P6 this has changed significantly. This is a big chance for NT, and
a big chance for the free unices. And i still see a factor of 2-3 between
the costs of developing software under NT and under a free Unix, so maybe
the latter will win :) And there are some software things that i consider
impossible to implement under NT, without taking a huge cost hit.
