Thanks, Martin. I actually had wvdial working on a TS-7260 board (ARM)
with a 2.4 kernel without any problems, so I don't think there is still
an ARM issue. With the 2.6 kernel I was able to avoid the divide by zero
error by loading the correct(?) driver - ts72xx_isa16550.ko - although
wvdial still does not recognize a modem on that port for some reason.
