freebsd stable - Oct 2006 - BCM5754 supported in 6.2 release?

I asked the question below a while back but got no answer.
Does that mean BCM5754 integrated GbE will not be supported
by 6.2 release at all? The HARDWARE.TXT file does not list
it, but the source code seems to have the BCM5754 support,
or at least so the CVS comments say.

Does anyone know when if_bge will support BCM5754 GbE? We
really hope to run FreeBSD on our Dell Precision desktops.
Thanks in advance!

Sincerely,
Edward

If the source code mentions support, then it most likely will be 
supported but has not made it to the docs yet. To be sure, download 
ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-i386/6.2/6.2-BETA2-i386-bootonly.iso
, boot it up and see for yourself.

Hi, thanks for your reply and suggestion.

I downloaded FreeBSD 6.2 Beta2 and tried to boot it on Dell
Precision 390. It failed with the same sympton as before
(upgrade 6.1 release by cvsup and buildkernel/buildworld).

The BCM5754 device is recognized (wrongly) as BCM5787, folloed
by a kernel trap 19.

This problem effectively makes FreeBSD 6.2 Beta2 unusable on
any new Dell Precision machines. Please help, anyone? Thanks
in advance!
