You can't be sure from the function name if it's just for
1.3 or for 1.3 and higher/lower. e.g. before this patch, the
pc_init_pci_1_3() function was used by both pc-1.3 and pc-1.4.

But I will change this, anyway: I will document only the non-trivial
cases (that don't apply to only one machine-type version), it should be
better than redundant comments.

Will be fixed in the next version.
