Situations like what you are saying are rare and/or one-time occurances. And if you look at drivers like if_ath(no offense meant towards Sam): ath0: <Atheros 5212> mem 0xf4010000-0xf401ffff irq 11 at device 0.0 on cardbus1 ath0: mac 5.6 phy 4.1 5ghz radio 1.7 2ghz radio 2.3 ath0: Ethernet address: 00:0c:41:15:5f:94 ath0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps ath0: turbo rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps The last 4 lines could easily go under bootverbose. I'd even wager that the second line can be hidden also; it provides little useful information for a normal boot. Scott
