[linux-lvm] can't pvcreate more than 64 dasds on Linux/390

I am using lvm-0.9.1_beta7-1 with TurboLinux6.5(2.2.19) over IBM
mainframe S/390. I tried to pvcreate 200 dasds(disks) together, than I'll
make them a vg, totally disk space around 500G.
    I can work with dasds whose major number is 94 (that is, 64 dasds in
total)all right. However, I fails to pvcreate those dasds whose major number
is 253, 252.... The message is:

[root at host96 block]# pvcreate /dev/dasdb[st]1
pvcreate -- invalid physical volume name "/dev/dasdbs1"

    I traced lvm kernel source and found that in
/usr/src/linux-2.2.19/include/linux/major.h, only dasd with major number 94
is defined. I think that's the reason pvcreate thought those dasds are
invalid.
    Any Solutions?
