Kickstart installation of a Dell PowerEdge 1300 at our
site fails during X setup. When running Xconfigurator
--kickstart on the manually installed system it exits
with exit code 2.

A little debugging revealed the problem to be in the
following part of the code in Xconfigurator.c:

    if (card_selected == UNLISTED_CARD) {
        unlisted_doprobe = strcmp(state->serverbuf,"I128")
&&
            strcmp(state->serverbuf,"S3") &&
            strcmp(state->serverbuf,"S3V") &&
            strcmp(state->serverbuf,"Mach64");
    } else {

When modifying this to

    if (card_selected == UNLISTED_CARD) {
        unlisted_doprobe = strcmp(state->serverbuf,"I128")
&&
            strcmp(state->serverbuf,"S3") &&
            strcmp(state->serverbuf,"VGA16") &&
            strcmp(state->serverbuf,"S3V") &&
            strcmp(state->serverbuf,"Mach64");
    } else {

it works find. This is just an educated guess, but IMHO
a generic 16 color VGA card should not have special clock
modes detected.

The output of the "X -probeonly" that is done for
clock detection is available under the URL in the
