Using [OEMBootFiles] Section with subdirectories in unattended Set

I try using 2 different versions of intels iastor/iaahci drivers (Version 5.5
and 7.x).

i copied the two different versions in 2 subdirs in the "$OEM$\TEXTMODE"
dir, and added
[OEMBootFiles]
disk1\iaahci.cat
disk1\iaahci.inf
disk1\iastor.cat
disk1\iastor.inf
disk1\iastor.sys
Txtsetup.oem
disk2\iaahci.cat
disk2\iaahci.inf
disk2\iastor.cat
disk2\iastor.cat
disk2\iastor.sys

when installing, i get no error, but the setup halts with a "can not copy
iaahci.cat" - and so forth for files in subdirectories.
the txtsetup.oem is btw. customized to support both versions of the driver.

is it possible at all to use subdirs or do i have to use them in "" ?
