Ok, with the patch it _does_ work with no flags, but it _does not_ work
with flags 0x20000. Here's the dmesg output:

You'll notice that the 'XX events for device with no tp' start recurring
when COM_BIGFIFO is enabled :-(
FWIW, I _did_ open up the box and look at the modem card; it has an
AT&T 16345 on it.
