No, it doesn't do that (well it never did for me, anyway).I agree you certainly don't want to mount /dev/sda (without a number appended).
Note that Apple partitioning is different from PC partitioning. When mounting a hfs+ partition, it looks like you have 4 or 10 partitions, only one of them (possibly sda2 or sda4) is usable, all the others appear to have zero length.
Well iirc they don't have zero length, but contain stuff like drivers or so (I'm not sure whether that is just a relict of old pre-OSX MacOS times, though, so nowadays hey could possibly really be empty).
I once saw this in a partitioning program of another distro; in Debian I haven't found a way yet to make these partitions visible.
You just need kernel support (either as module or compiled in). The kernel configuration variable is CONFIG_MAC_PARTITION (for mac partitions, anyway), should you compile it yourself. linux-image-2.6.18-5-486 does have that compiled in already, as can be seen in /boot/config-2.6.18-5-486
If your /dev is being handled by udev (as is the case for etch), then you can easily check whether the kernel understands the partition table: if there's not only a /dev/sda, but also /dev/sda[1-9]* device files present after attaching the disk, then the kernel understands the partitioning just fine (you can also check kern.log).
I guess you mean that you haven't found a way to get a partition listing with sizes. On Debian on Macs, the package "mac-fdisk" is being installed automatically (at least that was the case with woody) which provides an "fdisk" program which could handle mac partition tables; packages.debian.org says that this package is only available for powerpc; strange, I don't see any reason for this (maybe it has some endianness bugs? maybe it's just because it provides a binary of the same name as the x86 "util-linux" package? If it's just the latter, you could probably recompile the mac-fdisk sources locally (not as .deb) and use that).
I'd just do an ls /dev/sda?* and then try to mount every shown partition in turn until you've found the right one.
