Yes, that looks more reasonable explanation for what you were reporting
in the previous message. I'm actually still using older kernel version
(2.6.17) and at least that seems to be working with DWL-650 RevP (with
the product id added to hostap_cs.c). Looks like I need to update my
kernel for the test system I use with Prism2/2.5/3 cards at some point..
I don't think that anything has really changed in the Host AP driver, so
this may involve changes isomewhere else if the initialization of this
card has indeed been broken completely between 2.6.17 and 2.6.19.
