Bug#501383: domU with 2.6.26 does not see more than 4G of RAM

["Nikita V\. Youshchenko" <yoush@debian.org>]

Package: linux-image-2.6.26-1-xen-686
Version: 2.6.26-5
Severity: normal

I've just tried to start kernel from linux-image-2.6.26-1-xen-686
instead of etch xen kernel in a domU.

Since that domU runs an application server with >50 KDE session
nortmally active, it required much RAM. Current setup is 15G.
That works with etch 2.6.18-6-xen kernel.

However, kernel from linux-image-2.6.26-1-xen-686 recognized only 4G.

Hypervisor version is 3.2.0-3~bpo4+2 (from backports.org).
xen-utils-3.2-1 in dom0 is 3.2.0-3~bpo4+2.
Both hypervisor and domU are 32bit.
