По сборке ядра - тут каждый затачивает сам.Что ставите? 9.2? amd64?
Могу дать общие общеизвестные рекомендации.
Выбирайте, оставляйте и добавляйте те опции, которые вам нужны.
ipv6 не используете? - выпиливайте
raid не используете? - выпиливайте
scsi или usb или sound? нет? - убираем
дискета, ком порт, параллельный порт, мышкка, клава пс-пополам (тогда есть usb? - соответств. оставить нужные опции в разделе usb для поддержки)?
ну и так далее
планируете использовать mpd? значит нужен NETGRAPH
а вот я IPFILTER не использую - у меня он закомментирован
планируете в IPFW фовардинг? - нужно IPFIREWALL_FORWARD
Приведу как пример для 9.1 amd64
лично я севухи "лишние" убираю (паранойя)) оставляю те что нужны (интел em fxp и дешевенький реалтек для проверок на всякий случай - вдруг интел сдох, а под рукой ничего нет,
хотя, в этом экстренном случае, нужные драйвера для дежурной левой сетевухи можно и модулем погрузить)
