quirk_detailed_use_maximum_size not being applied

Description of problem:
The radeon (and other?) driver appear to have a quirk to handle some bad monitors/panels that return incorrect physical size. In this case:
static Bool quirk_detailed_use_maximum_size (int scrnIndex, xf86MonPtr DDC)
/* Bug #10304: LGPhilipsLCD LP154W01-A5 */
if (memcmp (DDC->vendor.name, "LPL", 4) == 0 &&
(DDC->vendor.prod_id == 0 || DDC->vendor.prod_id == 0x2a00))
However, this does not appear to be being applied in this case:
(II) RADEON(0): Manufacturer: LPL Model: 0 Serial#: 0
(II) RADEON(0): Max Image Size [cm]: horiz.: 33 vert.: 21
(II) RADEON(0): clock: 71.2 MHz Image Size: 289 x 21 mm
(II) RADEON(0): Using exact sizes for initial modes
(II) RADEON(0): Setting screen physical size to 289 x 21
As a workaround Option "IgnoreEDID" "on" appears to work.
Version-Release number of selected component (if applicable):
This actually appears to go as far back a F8 - not using the quirk.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
Still present in xorg-x11-drv-ati-6.11.0-10.fc11.x86_64
Can this get fixed? It makes the system almost unusable because the text size is so huge. You can't even see the login screen properly.
Still present in xorg-x11-drv-ati-6.12.2-14.fc11.x86_64.
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command
yum upgrade --enablerepo='*-updates-testing'
Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .
Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
