I've just tried it on my 1GHz iBook and boot time dropped from 74s to
60s. That's timed from selecting a bootloader option to the root prompt
appearing, less the time taken to type in my luks/dm-crypt passphrase.
Most of the saving came in the early part of the boot process, the part
before the password prompt (which comes from bootmisc AFAIK). It looked
like the udev stuff happened quicker, but I can't quantify that.
Anyway, a 20% reduction in boot time is nice, wherever it happens. Thanks
for the pointer.

I saw no errors, so they are certainly WFM compliant :)
