I remember some PCI errors showing up during boot with older kernels
that were eliminated in later kernel versions(2.0.32+ ?), but, of
course, I can't tell whether this applies to your situation.
What exacly does 'can't initialize the modem' mean? I had a file
permission problem with the /etc/chatscript/provider script that caused
pppd to freeze when it tried to use the chatscript. What does the end
of the ppp.log look like? Use plog to see this.
