With Linux 2.5.54 I'm getting an oops in the riva framebuffer driver that didn't
occur with Linux 2.5.53. It seems to be related to aforementioned changes. Trace
copied by hand because I have no serial console.

EIP is at fb_copy_cmap + 0x7f/0x140

Trace:

hide_cursor + 0x75/0x90
get_default_font + 0x209/0x2a0
updatescrollmode + 0x4f3/0x770
rivafb_set_par + 0x88/0xe0
fbcon_bmove_rec + 0x132/0x1f0
set_origin + 0x11d/0x190
clear_buffer_attributes + 0x1aa/0x1d0
put_driver + 0x2f/0x40
do_pre_smp_initcalls + 0x3a/0x160
do_pre_smp_initcalls + 0x0/0x160
show_regs + 0x5/0x18

The card in question is a Geforce 2 GTS.

If more info is required to help solving this problem, let me know.
