[Q][CM10.1] How to change the WiFi mac address - HTC Amaze 4G

Hi!
How do I change the WiFi mac address of an Amaze phone?
I got two Amaze phones that I put Sport's CM10.1 on them.
Problem is both have the same (well known!) mac address. Seems like either CM10.1 picks a fixes address, or perhaps the process or rooting it cause the mac address to be reset?
I tried searching for ways to change it. Some posts require using busybox, however, that's temporary.
Some posts refer to change it in an nvram.txt data somewhere in /data/misc/ (or similar, don't have it handy), however, I do not have that file in any of the phones. I do not know what format I would have to put it in if I were to venture to do it. I found one example of a different phone and it was a rather complex file with all sorts of settings, which makes me cautious about even trying something and possibly breaking the format of the nvram on the phone.
Thanks!

Thanks for the reply, however, this is not a great solution, as it's rather invasive. I'm also finding that this image I am on is stable and yields good battery and it has the latest 4.2.2, so I am trying to avoid major changes like a rom from a different device might be (I'm new to this too ..).
Here is what I have tried:
brute-force search on the zip file that Sport posted
brute-force search on the phone itself via a root shell
searching various other files and forums
the brute-force search on the phone found the mac address. This is what i did:
find -exec grep -iH '00:d2:8b:43:9f:fd' '{}' \;
which yielded:
/sys/devices/platform/msm_sdcc.4/mmc_host/mmc3/mmc3:0001/mmc3:0001:2/wl12xx/ieee80211/phy1/macaddress:00:d2:8b:43:9f:fd
/sys/devices/platform/msm_sdcc.4/mmc_host/mmc3/mmc3:0001/mmc3:0001:2/wl12xx/ieee80211/phy1/addresses:00:d2:8b:43:9f:fd
/sys/devices/platform/msm_sdcc.4/mmc_host/mmc3/mmc3:0001/mmc3:0001:2/wl12xx/net/wlan0/address:00:d2:8b:43:9f:fd
However these files are in a "/proc/-like" mounted device that is read-only. These files look like status files from the OS, so even if I had been able to change them, it looks like the changes would vanish after reboot, and even if that would not be the case, it would not have changed anything.
Any ideas?

This is the solution for permanently changing the MAC of the WiFi in the Amaze (ruby) phone:
su -
mount -o remount -o rw /system
cd /system/etc/firmware/ti-connectivity
calibrator set nvs_mac wl1271-nvs.bin 00:d2:8b:XX:YY:ZZ
cd /
mount -o remount -o ro /system
change the XX YY ZZ to any other (hex) numbers as you please.
(The assumption is that you are connected with adb shell)
