Hi, I've been working on the problem described below, I have found that the silicon motion driver under Solaris has a problem accessing some device registers when using MMIO. My solution was to implement the "NoMMIO" option in the driver (at least partially anyway? Sufficient to get XFree86 up and running under Solaris) My efforts are attached, as a patch to the silicon motion driver. The patch seems more of a workaround though, since I've not discovered the why MMIO does not work correctly.
One problem remains, exiting XFree86 back to the Solaris text console results in a
blank screen, I think this is down to a few device control registers not being
restored correctly, forcing both foreground and background colours to be the same.
Best regards,
Simon.

Hi Marc,
I tried installing the aperture driver, but this had no effect on my system.
I'll look into the Int10 driver when I have some spare time...
Cheers,
Simon.

Here's something you can try on the Solaris side. Do everything as
root.
Install the aperture driver. Intructions for this are in
README.Solaris.
Ignore the part of it that says the aperture driver shouldn't be
required in
your situation.
After the reconfiguration boot back into Solaris, but before starting
the
server, ensure that /dev/fbs/aperture exists and move (or rename)
/dev/xsvc.
Now start the server.
I can't promise that this'll work, but if it does, you'll end up with a
functional setup (and I have changes to make for the next release).
If this
doesn't work, it's likely Solaris clobbers the BIOS data the server
needs, in
which case changes to the int10 module will be needed to always
re-initialise
the adapter.
Marc.
