Don't read from 0xf8000090 during MacOS (8.5, 9.0) installation. Is this an

OpenFirmware check for OldWorld 604-based machines?

XXX I have code pending that makes it possible to use PowerMac ID #3035 and
model 510 (PowerMac G3 Series). However, I have a regression with one of my
MacOS 8.6 disks. This is non-standard anyway since it was installed from the
iMac DV 8.6 discs ("yellow" not generic) with MOL -- SheepShaver can't cope
with it.

So I am not surprised it breaks. Otherwise, 8.5 -> 9.0.4 were fine with it.

BTW, the "regression" is Native Resource Manager is not installed and the
boot gets mad later. FWIW, it's the same as for MacOS 9.1. A resource is
very likely not loaded.
