Fix the STI console to be able to execute either the 64-bit STI ROM code
or the 32-bit STI ROM code.
This is necessary on 64-bit only machines (e.g. C8000 workstation) which
otherwise won't show the STI text console on HP graphic cards like
Visualize-FX5/FX10/FXe.
When calling 32-bit code from a 64-bit kernel one may need to copy
contents on the CPU stack from high memory down below the 4GB limit.
