"make oldconfig" asked about 20 questions, I answered the default to all.

Dell Inspiron 530
Core 2 Quad 2.4 GHz (130W)
4 GB ? ? (n-n-n-m) ... but it's four sticks
Dell cheapo mobo

(it's a new box with a quad core.  I was curious.)

"time make -j 5" (on ted's advice) first run (ie. no significant caching):
"real   7m16s"

Holy crap - that included building all the modules too.  I may not
dread "make" quite so much in the future.

I'd like to do a comparison run on my old Athlon 2700+ from 2003, but
realistically I'm unlikely to get around to it and it would probably
cause no end of problems being a 64 bit config on a 32 bit machine.
