Lpc2000

That seems a bit... unusual. I haven't looked at the code in detail, but we 
have some interrupt driven UART code (the usual ring buffer routines) in 
our ICCAVR examples directory and they don't look too complicated. May be 
your can d/l our demo and just look at that portion for inspirations.

The ARM devices generally have a hard to use interrupt architecture, just 
because each device family usually have some sort of VIC (vectored 
interrupt controller) and each one could be quite different from another. 
e.g. LPC2000 UART interrupt handling is probably quite a bit different from 
SAM7S interrupt handling and the VIC code can be quite tricky to get right. 
In that sense, the AVR is easier to work with.
