    Quoting James Simmons (jsimmons@infradead.org):

    I am the happy owner of a "Club"-branded Radeon9200 video card. Here
    are my experiences using your diff.

    My card has a PCI id of 5964. Here you can read the output of 'lspci
    -vvv' for it:

    The only 9200 listed in pci_ids.h had an
    id of 5960. I added a new line, as follows:

    --- pci_ids.h~ 2003-10-16 08:26:14.000000000 +0200
    +++ pci_ids.h 2003-10-16 09:12:22.000000000 +0200

    /* Radeon R300 (9700) */
    (I did not know how to call it. _Yz did not exist, so I grabbed it. Is
    there any logic in these codes?)

    Then I added the new ID to aty/radeon_base.c:

    Again, I just blindly duplicated the entry for the other 9200. Now the
    stuff compiled, but if I chose to make a radeonfb module, I got a
    message stating that

    WARNING: /lib/modules/2.6.0-test7/kernel/drivers/video/aty/radeonfb.ko needs unknown symbol release_console_sem

    Well, I compiled the fb stuff in kernel. The card was eventually
    recognized:

    radeonfb_pci_register BEGIN
    radeonfb: probed DDR SGRAM 131072k videoram
    radeonfb: ref_clk=2700, ref_div=12, xclk=16600 from BIOS
    Starting monitor auto detection...
    radeonfb: Monitor 1 type CRT found
    radeonfb: Monitor 2 type no found
    radeonfb: ATI Radeon Yd 9200 RV280 DDR SGRAM 128 MB
    radeonfb_pci_register END

    (BTW what does "type no" mean? I have a monitor connected to the DVD
    plug, as well as my normal LCD monitor on the VGA plug - both monitors
    show the framebuffer image)

    But, always at 640x480. My adding

    video=radeonfb:1280x1024-32@60

    to the append line in Lilo did not cause any visible effect. Running
    'fbset 1280x1024-60' did indeed change the resolution on my two
    monitors (although with wrong number of lines and columns - unpleasant
    but I know how to fix that). But if I then changed to another virtual
    console, both my monitors went black. The LCD one complained that it
    was fed invalid frequencies (103.1 kHz horizontal, 197.8 Hz
    vertical). At this point, changing virtual consoles had no effect
    anymore, and if I typed Ctrl-Alt-Del, the machine would beep (meaning
    it caught the reboot request) but nothing would happen
    thereafter. Only a hard reboot would give me back the machine.

    (There is also this fancy special effect: the cursor is not
    full-white, but with cute fractal-like black pixels inside.)

    What can I do to help debugging this code? (I am not bk-enabled!)

    Carlo
