KDM Screen Size
I've seen posts where this has been asked but never seen an actual solution.
KDM ignores the screen resolutions set in KDE and Xorg.conf. My display is a 1440x900 widescreen LCD. I've set up Xorg and my KDE desktop to use that resolution and it looks great, but when the KDM login screen comes up it's back to something like 800x600, the login box isn't centered and it's too big. Using Crtl-Alt-+ or - changes between what looks like 640x480 and 800x600, (bad and worse).
I've been able to use kdmrc, Xsetup and Xstartup to set backgrounds, screensavers, etc but no matter what I haven't found a way to set the login's display size to a larger area. Every time I log in the screen resoultion is switched to 1440x900, but logout and it switches back down and looks bad again.
Is there a way to tell KDM what screen resolution to use?

It looks like the screen resolution is not properly set in xorg.conf but only in KDE.
KDM Screen Size
Sorry I thought I had specified that already. My xorg.conf includes 3 modelines, 1440x900_60, 800x600_60 and 1024x768_60. The default depth is 24 and the 1440x900 resolution is the first entry in both the 24 and 16 color depths. The display size is specified per dpyinfo, my virtualsize is specified as 1440 900 ... so I think I have xorg.conf covered. per my experience with X the server should always use a default 1440x900 @ 60hz resolution with a color depth of 24, but KDM doesn't, it's still showing a smaller desktop size with the login widget too large and out of place.
It's possible that KDM is actually usiing 1440x900 but with a 70hz refresh which also makes the screen look too large, but with all that specified in xorg.conf I thought it should be taken care of. Xorg.0.log shows the refresh rates and modelines being accepted, no errors so I'm kinda stumped.
KDM Screen Size FIXED
OK the problem was that I didn't use the "modeline" name as the "mode". A bit of stupidity on my part not realizing that 1440x900 was a different resolution mode from 1440x900_60. Once I matched the modes to the modelines it worked. So the short howto for cleaning up your screen, once X is functional, is:
1 - check the Xorg.0.log for the probed dimensions of your monitor
2 - set the dimensions as the displaysize in the Monitor section in xorg.conf
3 - use the gtf command to get your modelines per your monitor's specs
4 - add the modelines to the Monitor section of xorg.conf
5 - specify the modelines as the modes to use in the Display section of xorg.conf
6 - restart X and should be working.
