Neo fast charge utility

Hijacking a bit:
On the topic of making the neo a usable phone (namely, overcoming the
terrible battery life), I'm trying to figure out how to get a USB
charger going
I have a Zap R12 (branded by Noma since I got it in Canada)
<http://www.zapworld.com/recharge-it-all> which is a Li-On battery
attached to a USB port. What I can't tell is whether I can source
500mA from this without damaging it. I can't find any specs around
that suggest I can, but I find a lot of end-consumers talking about it
"charging slowly" (i.e. suggesting that it only gives 100mA, as I've
observed). Does anybody know how I could test if it is safe to draw
500mA from this? I can always try and see if I smell burning--the
charger was a gift, I am not especially attached to it--but it would
be nice if I had an intelligent attack on this problem instead.

there's also Ladyada's MintyBoost
<http://www.ladyada.net/make/mintyboost/> which seems like it might be
designed to give 500mA, but I don't see any intelligent USB-compliant
chip in there that the moko could ask "can you give me 500mA?" so I'm
unsure.

for the record, all thunder does is write
"fast_cccv" or "closed" to
/sys/devices/platform/s3c2410-i2c/i2c-adapter/i2c-0/0-0008/chgmode
depending on what mode you want, and wrap that up in a nice OM GUI.
Any hope for a qtopia version?
