OK, I went out and briefly tested the sun4m kernel on a few of the
different machines I have. Here's the results:

Model                                   PROM Rev.       Result
LX                                      2.9             3,4,5
SS10 SX 40Mhz w/Cache                   2.13            2
SS5 85Mhz                               2.15            1
SS20 50Mhz w/Cache                      2.15            2
SS20 100Mhz HyperSPARC RT625            2.22            6
SS10 40Mhz w/Cache                      2.10            3,4,5

1. panic: bootstrap: could not get interrupt node from prom
2. le0: card failed to initialize
        ledma: buffers at 0xfd000000 have become unwritable!
        panic: ledma: to many DMA failures.
3. esp0: sync nego not completed!
4. le0: lost carrier (using 10T port, no network access)
5. Successfull boot to multiuser!
6. Illegal Instruction (fails trying to load primary boot)

Are there different link flags I should be trying for TPE or AUI?
Everything I have is on TPE.

Is there any chance of getting VME support? I can then test out
the old galaxy boards (600 series).
