Little preseed problems

[MaTa <emfamandraescriure@gmail.com>]

Hi

I'm trying to preseed a Lenny 5.0.1 installation and all works but some little options doesn't starts. 
Please can you help me with any?

1 ) cdrom-checker doesn't start with "d-i cdrom-checker/start boolean true"
2 ) OEM installation doesn't work with "d-i oem-config/enable boolean true"
3 ) Xorg configuration it's de default and doesn't work with with:
"xserver-xorg xserver-xorg/autodetect_video_card boolean true"
"xserver-xorg xserver-xorg/autodetect_monitor boolean false"
"xserver-xorg xserver-xorg/config/monitor/selection-method select"
"xserver-xorg xserver-xorg/config/monitor/mode-list select 640x480 @ 60 Hz"
"xserver-xorg xserver-xorg/config/display/modes multiselect 640x480"
"xserver-xorg xserver-xorg/autodetect_mouse boolean true"


I attach the complete preseed file.
Sorry for my english and thanks a lot in advance
