Out of curiosity, what firewire card and more specifically what chipset is
it using?

In the past I could only ever get TI-based firewire chipsets to work
reliably in Linux.  All of my current STBs have abandoned firewire, but
knowing what cards work in Linux could be useful if I end up switching
providers to ones with firewire in the future.  I found using the firewire
channel changing far more reliable / easier to configure across OS upgrades
than the lirc based approach I currently employ.
