yes. it's loaded now and in initrd order is:
insmod /lib/modules/2.6.22.18-2/kernel/drivers/md/md-mod.ko 
insmod /lib/modules/2.6.22.18-2/kernel/drivers/md/raid1.ko 
insmod /lib/modules/2.6.22.18-2/kernel/drivers/scsi/scsi_mod.ko 
insmod /lib/modules/2.6.22.18-2/kernel/drivers/scsi/scsi_transport_spi.ko 
insmod /lib/modules/2.6.22.18-2/kernel/drivers/scsi/sym53c8xx_2/sym53c8xx.ko 
usleep 5000000
insmod /lib/modules/2.6.22.18-2/kernel/drivers/scsi/sd_mod.ko 
insmod /lib/modules/2.6.22.18-2/kernel/drivers/scsi/scsi_wait_scan.ko 
insmod /lib/modules/2.6.22.18-2/kernel/fs/mbcache.ko 
insmod /lib/modules/2.6.22.18-2/kernel/fs/jbd/jbd.ko 
insmod /lib/modules/2.6.22.18-2/kernel/fs/ext3/ext3.ko 
mdassemble

when i use debuginitrd=sh i see that all modules are loaded, i receive
shell and then after some time (2-5 seconds) sd? discs are detected.
