200MB no longer enough for NetVM with iwlagn driver

Previously, when using the 2.6.34 kernel in a NetVM, the iwlagn driver was starting fine with just 200MB (when the NetVM was the first VM started in a freshly booted system). Now, with the 2..6.38 kernel, I need at least 300MB for iwlagn to load, or I get an error about inability to allocate continues DMA memory.

Strange, 200MB is still enough for me on 2.6.38 (e1000e + iwlagn).
Anyway I've slimed down initramfs somehow (http://git.qubes-os.org/gitweb/?p=marmarek/kernel.git;a=commit;h=3bce01fb11ade09cc46b6333011770d61309bdf0) to not allocate 50MB at startup...

Works fine on my other laptop, but also with iwlagn. Closing.
