You remember correctly, and also G5 (PowerPC 970) are 64-bits natively
and will happily run a 64 bits kernel (and even userland) in Linux
(including Debian), so this is for G4 (PowerPC 74xx) only (and G5
running OSX, or NetBSD which doesn't have a 64-bit kernel / userland
yet).
[this is for PowerMacs - some newer, embedded, 32 bits powerpc also
have AltiVec, although the one in the AmigaOne X5000 doesn't].
Cordially,
