Ok, here's what I did.

* merge 'master' branch of
git://git.infradead.org/users/linville/wireless-next.git with -rc8 in
order to get da3ba88a9996.

* apply your attached patch with the Realsil facelift:

patching file drivers/net/wireless/rtlwifi/rtl8192se/hw.c
patching file drivers/net/wireless/rtlwifi/rtl8192se/reg.h
patching file drivers/net/wireless/rtlwifi/rtl8192se/sw.c
patching file drivers/net/wireless/rtlwifi/rtl8192se/trx.c
Hunk #6 FAILED at 540.
1 out of 6 hunks FAILED -- saving rejects to file drivers/net/wireless/rtlwifi/rtl8192se/trx.c.rej
patching file drivers/net/wireless/rtlwifi/wifi.h
Hunk #1 succeeded at 1328 (offset 3 lines).

(had to apply hunk #6 by hand though)

* build

Yeah, I'm sorry to confirm that your pessimism turned into realism :-).
It froze in under 20 mins. Ran the driver with default module parameters
though.

Looks like I'll have to test the Realsil tarball after all. Question, do
I simply overwrite the subtree under drivers/net/wireless/rtlwifi/ with
the files from the tarball?

Also, any preferred module parameters settings you want me to test?

Thanks.
