[Wine] wine on AMD64 in an IA32 chroot environment

I have got a problem with wine running on an AMD64
64-Bit linux running in an IA32 chroot environment.

I used an extra-partition for the IA32-chroot environment.

If I boot into this 32-Bit Linux directly, wine runs Ultima Online quite 

But if I boot into the 64-Bit Linux and then chroot to the 32-Bit 
Ultima Online exits with an error and reports that there is not enough 

Well, I use these lines in my fstab to setup the chroot, while /mnt/sda7 
holds the extra partition:

#x86 32 chroot
/home           /mnt/sda7/home  none    bind            0       0
/tmp            /mnt/sda7/tmp   none    bind            0       0
/dev            /mnt/sda7/dev   none    rbind            0       0
/mnt            /mnt/sda7/mnt   none    bind            0       0
/sys            /mnt/sda7/sys   none    bind            0       0
/proc           /mnt/sda7/proc  none    bind            0       0
/var/tmp        /mnt/sda7/var/tmp  none    bind                 0       0

While reading through the strace report, I found an node, that wine 
opens /proc/meminfo .
Running in AMD64 mode, it looks like

On an IA32 kernel, it looks like:

VmallocChunk:    88052 kB

May this difference cause wine to report a wrong memory size to Ultima 
Does anybody know a work-around for my problem?
To whom I must talk about this?
I suppose I need some help, please.
