Im not sure what 'switched off' means, so heres the 'relevant' parts of 
the .config
Now that I look at it, Ive obviously not attended to the advice in 
README.INSTALL.

This config worked nicely with ntp, FWIW.

Given that this is a laptop, Id like to keep ACPI and/or CPU-freq if 
possible,
but I'll try some combos to see if any work for both the battery,
and for the perl tests.  I'll try a conservative/recommended config too.
Any suggestions or test-requests are welcome.
