Thats funny. Did you aply my patch to the original 20000725 version?

Aha, Dell Inspiron 7500!
There was some extra stuff in the Linux driver for it.
I have recreated my patch (mstr2_spk.patch2) to include them.
Please aply the new patch to the original 20000725 version source code!
And also, I added a small patch (mstr2_gpio.patch) that should print
GPIO values. Aply GPIO patch after the mstr2_spk.patch2!
Let me know how that works out.
BTW, I'll be out of town for few days. So my reply may get delayed. sorry.
Thank you,
Haro
