To package or not to package?

Hi all, Since where I work I probably will need packaging our products in rpm format, I would like to take this chance to help somehow the community while learning how to properly do it. I am interested in packaging the kernel driver for TI ACX100/111 wireless network cards, but this poses some issues: - currently an older version is present in Dag Wieers repo (thanks Dag!!). Should I ask him "permission" to work on it before doing anything? would it clash somehow if present in both repos (dag & extras)? - How do I deal with the card firmware, which is released as a binary module (guess much like the intel centrino one) - What kernel version should it target? the latest rawhide, the one in Core 2, the last in updates... Thanks for you thoughts Gianluca
