CyberStorm official versus private flashes

[LoadWB]

On the Phase5 website at a1k there are two "private" flashes.  I'm going to re-flash my Cyberstorm MK III today as I cannot get the bootmenu to come up and I saw these two private flashes.  Has anyone used 44.69 or 44.71?  I don't have anything which would need OpenPCI so 44.71 probably isn't in my plans.

EDIT: Just thought, I'm using a Picasso IV (PIV)... is there any chance the bootmenu is producing a screen mode which my monitor doesn't like coming through the PVI, thus making it look like the menu is not coming up?

Yup, solved.  I took the Indivision from my other 4000D and I can now see the boot menu.  So it's apparently a screen mode the PIV either does not pass or my monitor does not like.

Now, my original question remains: has anyone used the private flashes and are there any benefits over the last official release?

Supposedly 44.67 includes a "No 31kHz screenmode" option to prevent the Phase5 and Kickstart bootmenus from coming up in a 31kHz mode.  I have to move my SVGA cable from the PIV to a Gonbes in order to use these menus.  I guess I could pull up the status information and see if that is really working or not.
