HOST:

WinXPsp3 32-bit with VT (dual quad-core Intel Xeon E5345 processors)
4 GB RAM
NVIDIA Quadro FX 3500 video card, 256 MB VRAM
VBox 3.0.6

GUEST:

Solaris 10 u7, 1500 MB RAM assigned to guest, 128 MB VRAM, guest additions installed
IOAPIC, ACPI, PAE, VT-x enabled

32-bit guest boots fine, NAT dropped packet problem (#4343) resolved. Network/internet connectivity good.

64-bit guest will not boot. Several USB controller errors come up, and then a page fault and return to GRUB.

Please help.

Page fault contains "bad kernel fault." Using 141415-10 kernel patch.

I have the same problem. First disable the USB2.0 EHCI Controller, this will allow you to boot. Next, try installing the latest version of Guest Additions.

I am still having problems with USB2.0 even after installing the latest guest additions, so you might have to live without it for now.

By the way, i am running OpenSolaris snv_122 guest, Vista Host.

3.0.6 Solaris guest additions were installed, and disabling USB controller has no effect on problem, for me.
