The problem is that vgacon and frame buffer consoles are different

vgacon is a console using the text modes of VGA cards. To stand a chance
of working it requires the boot firmware of your board to execute the
VGA BIOS code on the graphics adapter. It works on PCs and possibly some
non-x86 workstations.

Frame buffer consoles (fbcon) use the graphics modes of the video card,
and chipset specific drivers.  I wrote the original asiliantfb for the
69030 chip. Saito.K & Jeanne replaced the 69030 support with 69000, and
it got into the kernel.

First, try removing vgacon and checking that you have fbcon enabled.
If that fails, try contacting the driver's authors. There's no contact
address for them in the source, though Google finds one other driver by
them with this attribution:
