Xorg 6.8.1 bug?

[Luo Hong]

Yesterday, I updated my X.org from 6.7.0 to 6.8.1, but display mode worked abnormally, so I had to downgrade it back to 6.7.0.
The problem is described below:
    I set "ModeLine" in xorg.conf according to "gtf" utility, but after the upgrade, new xorg 6.8.1 seemed to not recongnize "ModeLine"
Whatever "ModeLine" configuration was, it just locked the display mode, the dot clock was locked at 108.00MHz, and the vertical refresh rate was locked at 60Hz. But when I downgraded back, everything worked well, is this a bug of 6.8.1?
   My display card is Radeon LE with R100 kernel.

Thank you and Best Regards,

Yours sincerely
