I have similar troubles to find a config that even only compiles. I got the
latest (well, a few days ago) 2.3 Kernel sources via bitkeeper. There seems
to be no default config file there.

During 'make xconfig', most of the options are sensibly set. My only changes
were to drop a bit of unneeded functionality, like certain exotic file
systems, or support for hardware that is not present in my sawtooth G4.
Afterwards, 'make dep' doesn't complain, but make zImage eventually fails
for the file "ide-dma.c", with the compiler complaining that the structure
"hwif" has no member "pci_dev". Apparently, part of the configuration thinks
that IDE doesn't sit on PCI, but the driver relies on the presence of a
PCI device.

In older kernels, there used to be a config option "Generic PC IDE support"
or somesuch, which was actually the core of all IDE functionality. This
option didn't exist in the 2.3 tree, so I cannot accidentally have turned off
basic IDE support (as is possible with 2.2, and is the favourite beginner's
error on non-PC systems).

So if anyone has a working config for a sawtooth G4, I'd be happy if I could
obtain a copy.
