Crucial has released a new firmware update for their M4 line. http://www.guru3d.com/files_details/crucial_m4_010g_firmware_download.html
Just updated mine from 000F. Worked just fine. If you use the Win7/8 installer and it says "finished_" for a while just wait, it will do a Coldboot after like 20 seconds.
After what happened last time I think I'll wait a little while. I do like the fixes mentioned though.
Heya, would like to run it too. But after the last firmware update not working with UEFI I kinda feel it's better to wait until some1 confirms it working. I'm too dependent on my notebook to try it myself.

The Windows based updater still does not work on my E758 board running Win 8. It start's reboots then gives me a boot failure. Rebooting the system fixes that error. Burning ISO to disk works fine. I've not tested the one major issue I think this may fix on my drive. When changing a BIOS setting that requires a reboot, changing the bclk for example, the drive disappears from the BIOS. I have let the drive sit on the BIOS screen for 5 minutes or so then reboot and it's revived. It's happened several times. No other issues besides that one. But it's scary enough having your drive disappear just from simply changing BIOS settings. Enabling or disabling HT does it too. Edit UPDATE I rebooted several times changing both HT and Bclk both together and independently and nary an issue detecting the drive. Finally something actually fixed!
