I have managed it in the past, experimentally.

The thing is, fdisk (and relatives) can't tell you about the
partitions on a Mac disk, because they don't understand the Mac
partitioning format. However, the kernel does and in the output of
/dmesg/ you should see the partitions listed. What I did was go
through and mount them all in turn until I found the ones with data
in. Confusingly, the Mac disk partitioning scheme used lots of little
partitions for holding non-filesystem data, so you may well find that
the ones with your actual drives in are some way into the disk - say
hda7 and hda8 when hda1-6 contain nothing readable.
