This is often related to interrupt contention. Probably your new machine
shares
the IRQ of /dev/cuad0 with other devices. If another device hangs on the
IRQ for
too long, the cuad0 silo will overflow and you are losing characters,
which
probably cause the gnokii conversation with the phone to fail. Try
tweaking your 
BIOS so that cuad0 doesn't share interrupts.

I've seen other suggestions, such as fiddling with HZ and modifying
sio.c but
this one is probably the simplest.
