Have not seen any oops for this problem yet so here are some data points. Stock 2.1.107, SMP, S3 video card (claims to be VESA 2.0 compliant), kernel compiled with serial console, gcc 2.7.2.3. lilo.conf contains
append="console=tty0 console=ttyS1,115200"
which works on 2.1.107 without any frame buffers.
VESAFB, no VGAFB.
No screen movement after "uncompressing linux", which is not surprising because the serial console says
Warning: unable to open an initial console.
This is not the "black on black" problem, the tty console is not getting registered. It then gets as far as opening the root file system for write and dies.

Wonderful things, serial consoles :). The oops then goes recursive, eventually blows the stack and the machine stops dead.
Another data point, something in this code is screwing with the keyboard. Press reset after this oops and the escape key does not stop the memory scan. Power cycle instead of reset and escape works.
VGAFB, no VESAFB.
After "uncompressing kernel", screen tries to roll up and displays "black on black". This time it registers the tty console. Serial console says
kmem_alloc: NULL ptr (name=unknown) fb0: VGA frame buffer device, using 32K of video memory kmem_alloc: NULL ptr (name=unknown) Console: colour frame buffer device 80x25 Calibrating delay loop... 66.36 BogoMIPS
Somewhere after registering SCSI drivers...

Escape key seems to be OK after reset for VGAFB.
