I'm not about this weekend either, so play will recommence sometime next 
week.   I'ts synching with a collection of uk.pool servers at the mo, 
just for the heck of it.  Turns out, it's USB ports wont supply enough 
power for even the GPS, unless something else was plugged in first to 
wake them up, so I need to modify the cabling to use the (soon to be 
redundant) PS2 mouse port for 5V power.

I'm quite impressed with the (so far) result, in as much as it's almost 
an "appliance" now.  You can power it down cleanly from the front panel 
Power button, FreeBSD recognising the request and doing the right thing 
all by itself.  Likewise, it'll boot and NTP run's just fine with no 
"user" input needed.

Off to play 4x4 stuff now.
