What I did was having a look at the kernel.
I inserted a few printf's to look at what was happening...
And hey: it worked! (with only the printf's added)
Seems like the DELAY's in the sioprobe code could use a little more
time?
anyway: I made the changes in /usr/src/sys/i386/isa/sio.c in the function
sioprobe.

ANd the modem works everytime now
