"disagrees about version of symbol module_layout" is saying the gslx680
module is not for the same kernel build as the kernel.
Try using:
https://github.com/jabjoe/linux-sunxi/tree/sunxi_3.4_gslx680
(Just add it as a remote, do a fetch, then checkout the
sunxi_3.4_gslx680 branch, that should avoid pulling all of git repo
down, just my bits)
and adding CONFIG_TOUCHSCREEN_GSLX680_TS to your build config.
It's a very rough branch as it doesn't take any of the history.

I still have no idea why it disagrees about module_layout and perhaps a manual
hex edit is needed. I have compiled the driver against my kernel so that should
not be there.

Ok, the driver is compiled now.
loads without force modprobe.
It creates an input device, but after:
i2c state isn't idle (0xf8)
STOP failed!
incomplete xfer (0xff)
reset_chip: gsl_ts_write 1 fail!
init_chip: reset_chip fail: -70
gslx680 1-0040: init_chip failed
The incomplete xfer is not 0x20 so the twi_id is 1 and adapter address correct.
Not sure what the 0xf8 / 0xff codes are but
I'm guessing something is being read sequentially from START. I think it wants
early suspend in the kernel source so the touchscreen is idle in low powered
state.
Still trying.
Can you give me the dmesg?
