I've got a X1950PRO and am using the radeon driver on F10RC with
1920x1200+1600x1200 and for the most part, it works fine. 

raptor> glxinfo -l | grep MAX_TEX
    GL_MAX_TEXTURE_STACK_DEPTH = 10
    GL_MAX_TEXTURE_SIZE = 4096
    GL_MAX_TEXTURE_UNITS_ARB = 8
    GL_MAX_TEXTURE_LOD_BIAS_EXT = 16
    GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT = 16
