It was either 2.2.20 or 2.2.25 which cleared up the debugging messages
when using the clgen driver. Just as a data point, I have an EGS
Spectrum card, which does not have this problem. I don't think that it
is making use of the hardware scrolling though.
I am running a home compiled 2.4.27. The clgen driver I'm using (from
my dmesg):
clgen: Driver for Cirrus Logic based graphic boards, v1.9.9.1
clgen: CL Spectrum board detected; RAM (2 MB) at $800000, REG at
$ec0000
Cirrus Logic chipset on Zorro bus
clgen: This board has 2097152 bytes of DRAM memory
Cirrus Logic video mode: 8 bit color depth
Console: switching to colour frame buffer device 100x37
Kernel command line:
root=/dev/sdb3 video=clgen:monitorcap:50;100;30;54,mode:800x600
This works with both the console and with X.
