Me got X50V also, great PDA. I got it running. You have to use a modified GAPI driver to get it to run. It is from a guy by the name of PicardBeta. Here is the site to get the GAPI driver.

The problem is that the X50v uses a special GPU for the framebuffer. It is the Intel 2700G GPU. The GAPI driver has been recently been modified further by a person named Emulamer. He made some new excellent changes.

Just install the GAPI tweak using the 1.11 version (the latest). It gives a great speed boost as well, at least 7to10 fold!
