If the refresh rate hasn't been explicitly specified, fd_find_mode currently returns the first mode with the requested resolution. Change it so that it returns a mode with the requested resolution and the highest refresh rate. Also export fb_destroy_modelist, which is used in uvesafb.

How about..? if (!refresh_specified) diff = 0; else diff = refresh;
best = -1;
for (i = 0; i < dbsize; i++) {
if (name_matches(db[i], name, namelen) ||

else {
- if(diff > abs(db[i].refresh - refresh)) {

diff = abs(db[i].refresh - refresh);
best = i;
}then
if (diff < db[i].refresh) {
