Try it with nofb and let me know if it works.  It looks like the problem
is the order in which the command line options are passed.  If it does
work, file a bug asking me to reverse the order than custom arguments
get added with the splash arguments.  Currently, the splash stuff is
always last.  If the kernel has more than one "console=" line, the last
one gets the kernel output, so the splash one is getting it.
