In order to get more data pushed to serial console before a hard freeze, would
there be any other debug options aside from using kdump?

I've found the following other module options for nouveau:

ie kernel cmdline opts:
drm.debug=14 nouveau.reg_debug=0x0200 log_buf_len=2M

(aka drm debug=(0-14??), nouveau reg_debug=0x0200, ...)

Think "nouveau reg_debug=0x4" for fb debug statements would be more proper?
