No, it doesn't. After fresh Windows install I was using only nVidia,
when I switched to Intel ("stamina") after installation and reboot it
booted in low resolution mode started installing Intel drivers only
then. Only after driver install I got normal resolution.

I don't know if two cards are a problem .... after switching to nVidia
the following two PCI devices are starting to be just normal "pcib"
stuff. And additional nVidia PCI device appears.
vgapci0@pci0:0:2:0: class=0x030000 card=0x81e6104d chip=0x27a28086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Mobile 945GM/GU Express Integrated Graphics Controller'
class = display
subclass = VGA
vgapci1@pci0:0:2:1: class=0x038000 card=0x81e6104d chip=0x27a68086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Mobile 945GM/GU Express Integrated Graphics Controller'
class = display
I think I don't have TPM (no option in BIOS at least).

Same here. I get two slightly different ASLs when booting into nVidia mode:
http://akson.sgh.waw.pl/~saper/FreeBSD/acpi/asl.diff
Looks like one memory region is shifted then.
Some things like IGDS and GPIC look interesting, maybe in theory it is
possible to switch graphic cards at run-time? :-)
Need to learn a bit more ASL :)
Can you post your ASLs somewhere?
