Consider a USB-VGA device for the video output - this may give you more hardware options. Linux
drivers (albeit with limited functionality) for these have appeared recently

How about the Beagle board?

PC104 - agreed. Try Technologic Systems @ www.embeddedarm.com.

With that setup i would have tried a PC104 base first.

I've got the following hardware requirement:
2 x RS232 port
Bluetooth (to talk to a mobile phone)
Ethernet (speed irrelevant)
USB (Controller)
A small qwerty keyboard
A small text LCD
640x480 Video output
NTSC video output
No particular processor power is required
Low power dissipation
Needs to fit into a box approx (mm) 100 x 50 x 150
I've designed loads of embedded hardware over the years but this
project will involve some internet stuff, and the bluet**th ;) so we
will be looking to make use of existing support and something like
Linux would be essential.
It would be nice to have something on which bluetooth actually works
;)
There seems to be a wide choice of hardware out there. The Gumstix
line is interesting but there appears to be no support contact
details; just a developer mailing list.
The video output requirement is a bit weird... we actually just need
to drive the text LCD, and currently I am doing a part of this using a
standard windoze XP machine with an 800x600 VGA output (DB15) driving
a cheap ex-Ebay VGA to NTSC converter. The converter is not a great
issue but is a significant size PCB and draws about 500mA at 9V.
