Ok, forget that, I rebooted without kms disabled and now I get 28 i2c/smbus
devices (most likely duplicates). Now scanning:
i2c-9 i2c i915 gmbus dpb I2C adapter
i2c-10 i2c i915 GPIOE I2C adapter
gives:
# i2cdetect -y 9
0 1 2 3 4 5 6 7 8 9 a b c d e f

and
# i2cdump -y 9 0x38
No size specified (using byte-data access)

So 1305 and 6726 actually look like the first registers indicated in the
datasheet.
