Well, the default kernel for powerpc on sarge will be 2.6.8. 2.4 is still kept
for people who may need it, and for some exotic configuration (think oldworld
machines, or prep with limited initrd size). For pmac hardware, 2.6 will
always be a better kernel. 

Debian-installer will also install a 2.6 kernel on powerpc per default, so all
new installs should have the 2.6 kernels.

Sure. but it is not the recomended thing to do. Same as you still ship X 3.3
(you still do, right ?), but if i ask you to run my nice Radeon 9800 on it,
you will probably suggest lots of un-nice things to me :)

Seriously, i have neither the hardware nor the knowledge to handle the 2.4 +
SMP + highmem case, and since upstream isn't really active on this anymore,
your patches are welcome. Consider that the 2.4 -benh tree has not been
updated since february or so last i checked, and that we are in fact
maintaining a forked version of it, i don't think it makes much sense to
over-burden ourselves in cases that would be much better supported by 2.6

Recent hardware means probably G5 machines, and in that case you _SHOULD_ be
using the 2.6 kernels. Debian-installer has already dropped 2.4 installers for
both power3 and power4/g5 based kernels.

And know that i got to all the effort of making the 2.4.26 and 2.4.27 powerpc
package mostly only for your benefit.
