 For relatively short (tens of seconds or so) periods of time, kernel
 successfully draws 1000mA from usb bus. according to measurements with
 multimeter charge current is >500mA.

 Sign of this event is
 [    6.500000] pcf50633 0-0073: usb curlim to 1000 mA
 [   47.680000] pcf50633 0-0073: usb curlim to 500 mA

 Mean that while booting 1000mA drawn for 41 seconds.

 Similar situation happens on suspend, but this were only visible while i
 added delay to printks for debugging.

 Tested for om-gta02-34 kernel from git. I think similar thing happens with
 other kernels too.
