Yes, the binary is downloadable from the link. If you need the source, you will have to use subversion to extract r19.
If 1.3.10 works, I will investigate the timing issues.
I built and tested SVN r19 last night. Unfortunately, at least for those with my specific likely hardware-related issues, it did not behave differently. It still did not receive DHCP or any packets upon first boot, but began working properly after resuming from sleep. In related news, I now have a new $18 Marvell based card, and a spare Intel card for a different machine.
On the bright side, hopefully this means that any recent changes in the driver only solved old problems and did not create new ones.
Even if it didn't work out for me, I (and I'm sure many others) appreciate your port as well as your engagement on the forums. Thanks!
