You've said in a later mail that you have 1GB of ram. This should be more
than enough.
The "problem" is effectively that the IOMMU code sets aside a certain amount
of memory for mapping translations, and you've tried to map more than it has
set aside.
Are you installing on serial console? Can you paste the output where
it dumps the device inventory?
Just as an example, this section:
Searching for devices...

The more of the boot log you can paste, the easier time we can have debugging
this.
