You problem has nothing to do with HostAP.  HostAP, like most other
drivers, needs and IRQ, and the PCMCIA subsystem fails to supply one for
your hardware.

Sorry for offtopic.  Please don't copy replies to hostap at shmoo.com

Support for TI bridges is actively discussed in the PCMCIA list (see
http://lists.infradead.org/pipermail/linux-pcmcia)

The current patch (it works with TI1410) is here:

That may be a different problem.  I'll really appreciate if you join the
discussion in the PCMCIA mailing list and test that patch.  Please post
the output of "lspci -vvv -s" to the PCMCIA list (not to the hostap list!)
