Then sounds like '"sharp,lq101r1sx03", "sharp,lq101r1sx01"' would be the 
appropriate compatible value. Do that, and you don't need a driver 
change.

Apparently you're right. The "sharp,lq101r1sx03" should be a slightly
improved revision of "sharp,lq101r1sx01". I see now that LQ101R1SX03 is
sold as a spare part panel for ASUS TF701T, hence these panels should be
entirely compatible with each other.

I mixed up the panel model which TF701T uses.

I compared datasheets of both panel variants. These panel have
differences in the pins configuration. Hence panels seems aren't
compatible in terms of hardware integration, although the difference is
small. They should be compatible from software perspective.
