Since it's probably a PCI device, maybe lspci would be useful.
It very often is.

(Note that one reason a really current live CD is handy is that it has
built in a recent snapshot of Martin Mares's pci.ids file,
http://pciids.sourceforge.net/ .  If the device's PCI ID is too new to
be fully recognised by lspci, however, lspci will still give you the
numerical ID, which you can then look up online in Mares's list.)

"dmesg | less" works as intended, here.  If it doesn't on your system,
then you have something broken.

My current preferred live CD for general purposes remains (whatever's
the latest release at any given time of) Sidux.
