Classic Setup resolution problems

I've added Transpercy and a custom background to the classic setup. And it all worked fine on the default resolution. All i've changed was:

HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.BitsPerPel",0x00010001,24
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.BitsPerPel",0x00010001,24

Since it was a 24bit 800x600 bmp image.

But when i changed the resoution of the setup to 1280x1024 everything stopped working. The background was black and no transpercy

HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.BitsPerPel",0x00010001,32
HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.XResolution",0x00010001,1280
HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.YResolution",0x00010001,1024
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.BitsPerPel",0x00010001,32
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.XResolution",0x00010001,1280
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.YResolution",0x00010001,1024

You can see i used 32bit in the settings but that doesn't matter i guess since i tryed with 24bit with the same results.

Could it be that SETUP_W.BM_ is too big?. The size is 1.5MB Too high resolution? I used 1280x1024.

Everything worked fine on 800x600 so why doesn't it now? (And no I didn't set it to use black backround in Nlite )

Some help would really be apreciated.

Btw. I only tested it on VMWare and Virtual PC.
