Is it possible to uninstall the replacement?

i can see that the following packages were changed during installation:

bme-rx-51 -> changed from 0.8.55+0m5 to 1.0-1
dsme-thermalobject-surface -> changed from 0.0.1+0m5 to 1.0-1
hald-addon-bme -> changed from 0.0.17+0m5 to 1.0-1
hostmode-gui -> changed from 0.4-1 (ii) to 0.4-1 (rc)
libbmeipc0 -> changed from 0.8.55+0m5 to 1.0-2
usbmode -> added

Thanks.
