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.
