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."

Since I don't think we can get it in for 2.6.8, and I'd rather not push
