Put on the 256 battery driver (but not certificates?) and after a soft reset so far so good! Also, one nice thing is before batti would say 100% instantly when I plugged it into power, now it actually reads a % charge.
Only had this patch for a couple minutes so I can't say how it's affecting battery life but unless it's drastic I'd prefer the more graduated battery guage. Anyway, I'm using this as a PDA (not a phone - I don't like all-in-one devices) so I can live with slightly cut battery life.
