Come to think of it - does the TT video chipset actually require screen
memory to reside in ST-RAM?

Yes.  Only the SCSI-DMA and SCC-DMA chips can address TT-RAM.

That's what I meant - the kernel residing in TT-RAM automatically will map
this chunk at kernel virtual address 0x0. Something in our mem_init logic
prevents using RAM with a lower physical address than was used by the
first chunk. I'm quoting from memory here - Roman Zippel might know the
exact answer to this.

If the kernel resides in TT-RAM all of ST-RAM is supposed to be used by
stram_alloc.
