This should fix the RTC century byte issue (fix merged upstream). Some patches were removed, in those cases where they became merged upstream.

+Subject: [PATCH 4/9] lenovo/t60: Enable brightness controls (native graphics)
+
+This makes the Fn Home/End keys work for controlling the
+brightness of the display. Value obtained by reading
+BLC_PWM_CTL when running the VBIOS (option ROM).
+
+On i945 legacy brightness control is enabled by a single
+bit in BLC_PWM_CTL. It's bit 16 or bit 0 (the other one
+reverses polarity). Set the bit to enable brightness
+controls.
