+ Pad V 103S
+
+This touchpad seriously dislikes init reports, not only timeing out, but
+also refusing to work after this.

+Subject: [PATCH 2/4] elantech: Fix elantech on Gigabyte U2442
+
+The hw_version 3 elantech touchpad on the Gigabyte U2442 does not accept
+0x0b as initialization value for r10, this stand-alone version of the driver:
+http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
+
+Uses 0x03 which does work, so this means not setting bit 3 of r10 which sets:
+"Enable Real H/W Resolution In Absolute mode"
+
+Which will result in half the x and y resolution we get with that bit set,
+so simply not setting it everywhere is not a solution. We've been unable
+to find a way to identifty touchpads where setting the bit will fail, so this
+patch uses a dmi based blacklist for this.
