Compaq b520 and trident blade 3d

[Paulo Henrique Baptista de Oliveira]

        Hi all,
        I installed slink and then upgraded for potato a Compaq 520 with a
Trident Blade 3D video card. My X is very small in horizontal mode. Anyone
knows a good modeline or a place to find one for this machine?
        Thanks,         Paulo Henrique
