Well, forget about it, sorry. I realized that the static table is not really necessary, the est.c tries to fetch the table list from ACPI. I recompiled the module once again and now the freq_list has a lot of possible frequencies, a lot more than before. Before I send the first e-mail there as only 6 and I could not set any of them because was listed as XXXX/-1. This problem is possible related to my bug laptop's acpi which has a lot of errors about allocating resources. By the way, I already sent a couple of e-mails to this list before, ACPI is a subject which I really like, maybe there is any kind of task (development) that I could accomplish to help the freebsd project and increases my knowledge about this? That's all, sorry for the annoyance with the previously e-mail. William.
