At any rate, that was the case on Win98 (the last time I encountered the problem, on behalf of a friend who wanted to put in a second hard drive). I don't know if it applies to XP, 2000, or Vista (and I'd prefer not to need to find out ... ).
NT and beyond are more sane, and you can re-assign the drive letters to make them stick.
Adding a 2nd drive containing only Linux partitions won't change the lettering sequence anyway - only FAT and NTFS partitions get letters.
