Enable 64 bit extensions?

[GVWR]

System Profiler says "64-bit Kernel and Extensions: No"
MBP5,3 with 4G of RAM and an Apple TS256A SSD.

I've tried several of the recommended ways to enable it but none have worked so far.
Any suggestions?

Restart, reboot holding the 6 and 4 keys. You are simply booted in the 32-bit kernel as is default on all Macs.

All macs except for this year's models of iMac and MacBook Pro, they start in full 64-bit mode by default.

right. My MBP boots in 64bit mode by default. However, it's really not that large of a difference compared to 32bit.

Except for Clear* USB Modems which don't work in 64-bit..smh
