ACE/SCE ??

I can't help on the shared IRQ one, although its a case of 'how to implement'
not 'can it be'. One warning with driving the UARTs that fast (apart from
the obvious dropped byte issues) the Linux kernel buffers serial data into
'flip buffers' it processes every timer tick. With 960Kbit+ you fill the
buffers before you get a timer tick, so may want to fix that up a bit or
bump HZ up
