Does the kernel detect the card when booting? You should see something
like the following when booting:
/sbus@2,0/SUNW,leo@2,0: leo at x:x
Also you should have leo ranges in /proc/iomem and /proc/ioport.
Ahhh... no, I don't see that in dmsg or anything in those proc files. I can
see the driver enabled in .config and I think that I'm running the appropriate
kernel but it's obvious that I need to go and check.
Am I correct in interpreting what you've said as meaning that X's "No devices
detected" actually means "I'm not seeing the appropriate device support in the
kernel"?
Seems this driver creates a normal fb device. Make sure you have /dev/fb0
and/or /dev/fb0autodetect.
You could try the fbdev X driver:
Driver "fbdev"
without specifying a BusID.

This is just to see if it detects a device. If it does the issue is with the
leo X driver. If it does not my guess it more toward a kernel issue.
Noted. Unfortunately the disc attached to the machine has started failing and
is rapidly getting worse so that's something that's got to be tackled before I
can progress this much further.
I'll be back, but I might be some time...

I've tried several combinations of BusID etc. without success.
Can PROM/prtconf see this device? I guess that would give you the
correct location, if any.
Best regards,
Yes, print-devs (?) shows it as /sbus@2,0/SUNW,leo@2,0 and I can see it in
the /sys tree.
lssbus doesn't work on this system but I've never tried running it on 2.6
before- I need to check whether there's an updated version.
I don't believe there's a hardware problem since it displays the Sun logo
with a Lion sitting on it when video first comes up, I do note however that
it's a rather magenta Lion and that console text is very slow.
This is a sacrificial development machine and I'm quite happy to experiment
on it. Which is fortunate since I tried installing Lenny earlier and am now
getting "Fast data access MMU miss" [sigh].
For the record, that last was a red herring- I was saying "?" to OpenPROM
rather than "help".
