Re: [Xen-users] b44 module fails to work with xen patched kernel

[Calvin Webster <cwebster@xxxxxxxxxxxxxxxxxxx>]

Does anyone know if there is any work being done on this?

Is there anything I can do to help move it along?

I'm in exactly the same position.

I've got a Dell E1705 with same hardware config as Woody (Same as 9400,
just branded different)

RE: "Bugzilla bug 187929: b44 module is not compiled into kernel-xen0"

This bug hasn't been updated since April 2006 when the b44 module was
disabled in kernel config due to "unknown symbol
dma_get_cache_alignment"

I've had this laptop for several months now, hoping Xen development
would catch up to the new hardware. I'm running FC5 but can't use VT
extensions in the Centrino Duo to run the xen kernels.

I'll be updating the bug with my data, but I'm not holding my breath.
Apparently there are too few of us using this driver, or too few
reporting it.
