It's probably the same interrupt latency problem that stopped my 16450
UART on the 386/sx16 notebook from working now; it worked well under
2.1.5.  (Ahem, that's with 115 kbps, i mean.)

I see them mostly as silo overflows, but i've also seen tty-level
buffer overflows...  Bruce is already alerted.
