OpenBSD 4.4/4.5 i386 installation on Dell Inspiron 6400 notebook.

I want to install OpenBSD 4.4 or 4.5/i386 onto a Dell Inspiron 6400 (a.k.a.
as a Dell Inspiron E1505) with the following hardware configuration:

Intel Core 2 Duo T7200 @ 2.0 GHz (dual core)
667-MHz FSB
2.0 GB RAM @ 667 MHz
Nvidia GeForce Go 7300 w/ 128MB dedicated (128MB shared) @ 1680 x 1050 native resolution w/ 32bpp color depth
160GB Samsung HDD (ATA)
Broadcom 440x 10/100 integrated Ethernet controller
Intel PRO/Wireless 3945 a/b/g 802.11 antenna
Optiarc DVD+/-RW AD-5540A (ATA) optical drive
SigmaTel High Definition Audio (codec)

My concern is that I will not be able to use the included X.org X11 drivers
to run the screen at 1680x1050 as I am able to do now with Win Vista Ult.

Also, I want to be sure that OpenBSD supports my audio hardware.

Lastly, are there any issues specific to the Intel 3945 wireless antenna with
OpenBSD?

I know that Nvidia makes binary drivers for linux and FreeBSD for the Nvidia GeForce Go 7300, but, I don't think these are compatible with OpenBSD.

I have also read that Xenocara is a possible solution for this issue.

Any advice would be appreciated.

Thanks,
