I have a HP Mini 1010nr with the Broadcom 4312 wifi card. I see this too, to get it to work,
I had to put in the install CD and add it as a source in Synaptic. Then I installed bcmwl-
kernel-source (which will install dkms, fakeroot and something else). This let me start using
my 4312 in 9.10 beta.

I have the install USB that successfully mimicked a CD to install Ubuntu. I assume from this comment that the missing drive may exist on the USB. Can anyone provide a step-by-step guide to do the process described above?

Marvelous system.
