I'm curious how the vga driver will be affected.
I have a few old systems still in production that run console only
that use ISA video cards.
The vga driver is a special case and would remain unchanged for now (it
initializes very very early through the backdoor and then attaches to
the isa bus even for PCI cards).
Another question I have is how the system will behave on old ISA-based
chipsets, like i430 or i440 and some chipsets heaving an ISA-bus (some
versions of i815 boards have the slot, while nothing was ever plugged in
A bad example of Linux kernels on non-MMX processors (unconditionally
halts on any non-MMX CPU, like Cyrix 150+) is the thing I really fear of.
Really it would be good to have some patch with a possibility to
integrate it with a kernel rebuild process to the system to support ISA
cards if it becomes necessary.
Sorry for my poor English.
