Because bugs@ is only for developers, using gnats or sendbug for posting bugs, I will post my (small) issues here.
Using Dell Inspiron 9400 laptop with latest snapshot (7/2/8), I have the following issues (also with older snaps);
- Disabled softraid in kernel ('disable softraid'), still mentioned for root in dmesg:

<cut>

scsibus1 at umass0: 2 targets

sd0 at scsibus1 targ 1 lun 0: <Netac, OnlyDisk, 4.12> SCSI2 0/direct removable

sd0: 125MB, 16 cyl, 255 head, 63 sec, 512 bytes/sec, 257984 sec total

- When lowering volume with aumix, the woofer in the laptop is not lowered in volume the same amount as the other speakers
- Processor T2600 is not fully recognised (unknown Enhanced Speedstep CPU in dmesg):

<cut>

Hope this helps with further development.
