toshiba satellite with black stripe on display

hi,
this week i installed freebsd 5.2 release on my toshiba satellite 2410-404
after i downloaded (nvidia.com) and installed the drivers the way i did it on freebsd 5.1 i started the x-server
the screen had a resolution with 800x600 and a ugly black stripe on the right side of the display
the same problem i had with freebsd 4.8, on 4.8 i used sysctl hw.nvidia.registry.SoftEDIDs=0 to solve this problem, on 5.1 x runs perfect without any entry in the sysct.conf
now i tried everything: 
(versions :  XFree68: 4.3.0,1   NVIDIA-FreeBSD: 1.0-4365)

/boot/loader.conf:

load_apg="YES"
load_nvidia="YES"

/etc/X11/XF86Config:

Driver "nvidia"

HorizSync  30-50
VertRefresh  50-60

i also put a modeline which i generated with http://xtiming.sourceforge.net/cgi-bin/xtiming.pl in it

/etc/sysctl.conf:

hw.nvidia.registry.SoftEDIDs=0
hw.nvidia.registry.Mobile= (i tried all from 0 to 4)

last week on 5.1 i had a resolution of 1024x768 without any problem...
