I did not get a response to this issue from the list but did get a solution from the folks at linuxant and thought I should post it just in case someone with the same issue searches the archives.
Hi,
to fix problems 1 and 3, please add the following line in your '/etc/rc.local' file :
hsfconfig --serial
This command will be executed at each boot and will make sure that '/dev/modem' points to '/dev/ttySHSF0'. It will also make sure that the '/dev/ttySHSF0' character device file is correctly configured.
For the second problem, it is quite possible that the tool read a database of drivers that came with the distribution and is not aware of other drivers such as our HSF driver. For the tool, every modem with 8086:2486 Sub 104d:8142 requires the 'serial_cs' driver, no matter what is currently installed to handle the modem right now.
