[rescue] SPARCstation 5: framebuffer resolution wont change

Well if that mode line wont work any suggestions as to what will ? , ive tried
the default 1024x768x60 with no luck.

I'm fast running out of options here and getting very frustrated indeed. Have
gone though 5 displays and many permutations of mode lines and set modes in
the PROM with no usable results.

I have been recommended a monitor to try that someone reports good results
with at the Sun default resolution(which seems to be the only one that my SS5
will happily output) but it is #80 on ebay and I only paid #30 for the SS5
itself so this would be somewhat of a last resort.
