Well, my inquiries are related to my research while preparing the
second edition of my book "Embedded Linux Primer", as opposed to my
duties as an FAE for MontaVista! Thus the posting from my personal
address.

Erm, my own misunderstanding of the problem contributed to the
confusion. I booted 2.6.29, saw that the kernel was passing
"platform:<driver>", using my test script that dumps env, (instead of
passing it to modprobe) and assumed it was still broken. Yes, my
2.6.29 does indeed contain those changes, and I'm sure it will work
correctly. Learn something new every day!!!
Thanks again for the help. I think I know enough about udev for
Chapter 18: Udev! ;)
Best,
Chris
