right here's a few little files:
http://rhombus-tech.net/community_ideas/kde_tablet/csivoltages.py http://rhombus-tech.net/community_ideas/kde_tablet/axp209.py http://rhombus-tech.net/community_ideas/kde_tablet/gpio_up.sh
in case anyone ever needs to program the AXP209 from userspace, the axp209.py (GPLv2, taken from u-boot, thanks to henrik, cut/paste conversion from c to python) file is capable of setting the LDO2, LDO3 and LDO4 voltages.
the gpio_up.sh is a little script which pulls the relevant GPIO pins for BOOT0 and RESET on the STM32F.

oleeeeee! that's the correct address of the gc0609 CSI camera!
the trick is that MCO (master clock out) is an ALT (alternative) function, once i'd set that correctly, it was up.
gpio_set_mode(GPIOA, GPIO_MODE_OUTPUT_50_MHZ, GPIO_CNF_OUTPUT_ALTFN_PUSHPULL, GPIO8); rcc_set_mco(RCC_CFGR_MCO_HSECLK);
a quick "soft reset" call and i managed to read the chip version: 0xa. woo!
