It is saying your modem is
Modem: Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Modem Controller (rev 03)
and it is a soft modem, with codec type SIL27
AFAIK this modem will work.
So to answer your question, yes.
Sometimes, these softmodems are slightly difficult to install. But at LQ or technion you will find help
If you are a newbie, maybe Suse, Mandriva, Ubuntu and some other might be better to start with than gentoo
If I read correctly,
The important bit is this one below, telling you it should even work with Knoppix
Scanmodem is a great tool, although sometimes overwhelming with information at first.
Read Modem/Slmodem.txt instruction for doing the slamr diagnostic.
Test the effectiveness of the hsfmodem package from http://www.linuxant.com/drivers/hsf/index.php
The knoppix Linux includes sl-modem packages with Smartlink drivers
Install the kernel-headers-2.4.27.deb
If necessary, set a symbolic link needed for slmodem compiling:
# ln -s /usr/src/kernel-headers-2.4.27 /lib/modules/2.4.27/build
as described in Modem/DriverCompiling.txt
Then install the two sl-modem/slmodem packages and follow their directions.
Thereafter the above slamr diagnositic can be run
