Mmm. Good :-)

I haven't yet looked at the storing of volumes in the EEPROM (which azt1605 
does, and azt2316 not). Requires some reverse engineering again, but that 
might provide a method.

When I find something, I'll also need to base my nicely simple and direct 
setup in the ISA match() method around a bit, since I'll certainly not know 
at _that_ stage. AZT1605 eeprom/config-register layout difference and it in 
fact supporting different IRQs for MPU-401 (and SB, but that's not used in 
these drivers)...

For now I've done a seperate azt1605 though and I sort of expect I'm going 
to try for just splitting the common code of into a galaxy.c and building 
the two modules from that. I'll not wait too long with submitting the next 
version, so you'll still have time to slap me around when you really do 
desperately want a merged driver (azt1605 is really utterly ancient by now 
though, and an even older galaxy I have will also need differences).
