Here it is:

http://spekt.net/~raadradd/freebsd/dmesg-acpi_disabled.boot
http://spekt.net/~raadradd/freebsd/dmesg-acpi_enabled.boot
http://spekt.net/~raadradd/freebsd/dmesg.diff

That's what grepping the diff for ata/ad0 spits out:

-atapci0: Reserved 0x10 bytes for rid 0x20 type 4 at 0x8080
[...]
-ata0-master: setting UDMA100 on AcerLabs Aladdin chip
[...]
-ATAPI_RESET time = 160us
+ATAPI_RESET time = 180us
[...]
-ad0: 16 secs/int, 1 depth queue, UDMA100
+ad0: 16 secs/int, 1 depth queue, PIO4

Please tell me if there's more I can do. Thank you.
