sysrq on serial console

Since the serial cleanups happened in 2.5, Magic Sysrq doesn't work
for me on the serial console.

It looks like the UART_LSR_BI bit needs to be set in the status
variable for the break character to be interpreted as a break in the
driver.

I doubt that it is actually broken, but it isn't immediately obvious
how that bit gets set. Is there something that I should have set when
the device was initialized to make sure that UART_LSR_BI is asserted
in "status" when the interrupt occurs?
