Now, for the actual question. :) The installer reports missing 
IOMMU/VT-d/AMD-Vi, however the machine's motherboard is an Intel Celeron N3350

 should have VT-d (unless it needs a specific kind of VT-d?). I am not sure 
about IOMMU, perhaps it is missing. Does the error message list those as 
alternatives of the same thing? Or is it that I may have VT-d but not IOMMU, 
and the error just lists them all if just one has not been detected?

Did you enable the possibly multiple virtualization options in your UEFI

There are actually no virtualization options in my UEFI config. I do get to 
turn off secure boot and some TSC stuff, but not much else. There's no vmx flag 
in /proc/cpuinfo (less that file after ctrl+f2 during installation), but 
apparently Qubes is not complaining about a lack of VT-x. There is a hypervisor 
flag, however.

It's possible your CPU supports the features, but not your motherboard's chipset and/or UEFI. Not having any options in the config for it is generally a bad sign. Check to see if there's a firmware update available for your board. VT-d implies there's at least one IOMMU, and VT-x is present on everything with VT-d.
