OK, worth fixing in this case.

Considering the kernel may fit into the first 4 MB, how much room does 
that leave for RAM allocated through stram_alloc?
Do we need to set aside some RAM right at the end of the kernel code 
segment for things like atafb (like we used to do in 2.2 or thereabouts)?

That's what I was suggesting - a stripped down kernel tailored to the TT 
could then
be 'distributed' (like you do with other stuff from your people.d.o 
page) to those
that need it.

Not that a total of 8 MB RAM would be a lot of fun to run today's kernel 
and userland on.
