[Arm-netbook] My little idea...

[Christopher Havel]

Schematic for the improved VGA circuit is DONE. I'll go scan it right 
now (after I fix the one bug I just realized I made).

This is the Olimex design I found -->

Again, mine's completely different. To enable 18b VGA you need one GPIO. 
Adding 24b capability requires a second GPIO. The circuit as drawn uses 
GPIO3 and GPIO4 to not conflict with the earlier schematics which use 
GPIOs 0,1,2 to drive the Ethernet port LEDs. Not that which GPIOs are 
used matters. Oh right -- the enable signals are active low, because 
electronics are almost always like that :P

Just a thought -- a few extra transistors and resistors here and you 
could have it work with 8/12/18/24b color as well -- but you'd need four 
GPIOs (base would be 8b, with 12/18/24 selectable with up to 3 more GPIOs).
