Comment 3 for bug 62206

It is worth noting that Asus does have Marvell linux drivers (and other linux drivers for the Deluxe P5B) on their support web.

IMO, that is the best solution at this time.

The driver worked just fine for me on Dapper and Edgy EFT. Yes, I have both (mostly) working on a P5B Deluxe. With Beryl, no-less.

I'm skeptical that this can be considered a bug, even with linux-source.

Yes, you have to build the vendor's driver every time your kernel image or modules get updated, but vendor-created drivers make a lot more sense than having the Ubuntu-Dev-Team (or kernel devs, or RedHat devs, etc) knocking themselves out every time a new IC chip is released... Just sayin' is all.

Hardware issues with Linux (or MS Windows, or MacOS, or BillyBobsOS) should always be directed to the hardware vendor first, and in the strongest (but fair) terms. They own the entire device driver and customer satisfaction development tree for your product. Period. If the vendor is unresponsive, don't buy from them and tell everyone you know about your experience.
