Even if you could run an AMD64 kernel on an i386 Userland it probably is not a good idea: FreeBSD == complete OS.
1) Try updating your Laptop bios to the latest
2) Try to configure your BIOS setup to any compatible/safe option if there is available
3) Your next move is to install FreeBSD 7 amd64 STABLE or FreeBSD 8 if you are brave enough..

Edit: If you have NVIDIA graphics chipset, then your only choice is 32bit due to the lack of 64bit drivers..

@TerryP
I disagree with the state that there is not any performance gain by using amd64 with less that 4G of ram. Of course , the more memory you add, amd64 processor family expands their capabilities, but there is always a performance gain of 5-10% at worst and all the amd64-specific registers are activated .

I was running FreeBSD 7 on i386 mode on my Acer aspire 1501 and when I moved on amd64 version I show noticeable performance improvement.
