G1 X long exposure ISO lockout?

Another poster noted when talking about his S100:

"Mostly I really like my s100. I had the s90 and s95. Both lovely. Like the s100, love the wide lens. BUT…

I've found (and Canon tech has confirmed) that ANY exposure longer than 1" will lock the user to ISO 80. That's it. No more stunning shots of the night sky at f/2, ISO 800 and 8". Or ISO 200, or anything else. The s90 and s95 were both capable of this.

I believe the s90 and s95 were CCD sensors and the s100 is a CMOS. But so what? My huge Canons are CMOS censors too and handle long exposures at any ISO the camera has listed. Why not the s100? Is this a software/firmware lockout so we're forced to "buy up" or is this some sort of legitimate hardware limitation?"

Does anyone know if the same limitation applies to the G1 X.

Thanks for the help.
