It seems your /etc/fstab is pointing to /dev/ad1s1a for your root filesystem:

vfs.root.mountfrom=ufs:/dev/ad1s1a

...but according to the dmesg output, the only disk detected is /dev/ad0:

ad0: 1918MB <SanDisk SDCFH-002G HDX 5.04> at ata0-master WDMA2

>From the prompt try entering 'ufs:/dev/ad0s1a' and see if it will
boot. If so, after the system is up, change the entry in your
/etc/fstab for the root filesystem mount from /dev/ad1s1a to
/dev/ad0s1a.

Others may have more insight into the particulars of using FreeBSD in
this sort of environment, so I'll leave it open for discussion
regarding stuff disk labeling and such...
