OK.  Thinking back to last time, I asked about being able to blacklist
some machines Residual Data (since it's crap on some, but I don't have
the dumps handy) and you mentioned that you'd like to do fixups on the
data since there's a few cases where the data is mostly good, just

with

one or two incorrect things.  And it doesn't look like either are
here... yet.

Could you do a 10/9 patch that adds a bit of help to the PREP_RESIDUAL
config option along the lines of:
"When this information is incorrect, it could lead to the machine
behaving incorrectly.  If this happens, please disable PREP_RESIDUAL

and

try again."

And change the existing "Unless you expect to boot on a PReP system,
there is no need to select Y." to "If you are running a PReP system,

say

Y here, otherwise say N."

As the residual support is runtime switchable can we also have a kernel
boot option?  That way we can switch it off for distro kernels.

A distro kernel would probably want it on by default (it makes more
machines work than it breaks).  As for runtime switchable, Leigh?

I'm working on it ;-)

You should note that IBM PRePs will not work at all without residual
data, due to this code in arch/ppc/platforms/prep_setup.c:

    if ( !strncmp(res->VitalProductData.PrintableModel,"IBM",3) )
        _prep_type = _PREP_IBM;
    else
        _prep_type = _PREP_Motorola;
