I haven't worked with IBM laptops for a while, but a few years ago at
least some of them had a minipci modem/ethernet card.  The modem in the
ones I worked with could be made to work in linux using the ltmodem
driver (binary only chunk + kernel wrapper code).  At the time I
remember it only ever worked when the kernel was compiled without SMP
support, so the code quality was not very impresive, but at least the
modem worked.  Perhaps other minipci cards don't work at all, or have
different drivers that may work better or worse.  It really depends
which exact modem chip it has in it and multiple choices exist.
