why isn't it possible to use some Sun-provided flash PROM-Update

Now that would be interesting. Running it could reveal some bugs in
Qemu's HW implementation and especially where we have made some bogus
shortcuts. For example, the boot sequence is not what a real Prom
expects, execution starts from 0xffd00000 instead of zero (reset
vector). I guess in the real HW, after reset the prom occupies all of
the address space, and one of the first things it does is to enable
RAM. Or prom lives near zero forever and RAM banks are higher.
To anyone who didn't already find it by himself:

EOL'd yet adds *>= 150 Mhz* Hypersparc support
