Hi,

A smarter ofwboot.xcf would not be a bad thing, thank you!

Makes sense, but does that mean enabled, as opposed to just being a 
feature list?

Yes. I've tried two CPU upgrades. The one I wanted to use was a 1.4 GHz 
7457 upgrade, but there are strange problems in NetBSD 2.0 which I could 
not isolate enough to know how to proceed further. It'd dump core in a 
number of different compiles, but in the same place in each of those 
compiles. I also tried OS X on the same hardware so I could confirm that 
both the memory and the CPU accelerator were not at fault.

The second accelerator is a 1.3 GHz 7455, which works fine under 2.0:

cpu0 at mainbus0: 7455 (Revision 3.3), ID 0 (primary)
cpu0: HID0 8450c0bc<EMCP,TBEN,NAP,DPM,ICE,DCE,SGE,BTIC,LRSTK,FOLD,BHT>
cpu0: 1300.00 MHz, 256KB L2 cache, 2MB no-parity L3 cache (PB2 SRAM) at 5:1 ratio

I had to get the machine colocated, so I just went with the 7455, but I 
still have the 7457 and can try it out sometime, if anyone is interested 
in looking at the toolchain problems. The 7455 is quite stable.

That's strange. It does sound like some sort of strange power-save thing 
that NetBSD isn't controlling.
