Great! Graphics support at this point, or is it still in the cpu server stage?

I've got one of the devices and was going to check some 5[acl] changes
Geoff had merged in, merge in any others from the Go 5[acl],
and (more originally) change the fp emulator to use VFP instead of 7500
instructions, so VFP can be made the default.
And 5i, I suppose.

excellent. i've just had time to look at the block diagram.
is there a jtag connector somewhere?
